Here are a few tips and a bit of tricks for people new to IRC

1. How to block all pm's: Press Alt+O (Or go to Tools->Options) scroll down and under the 'Other' section click on 'Lock'. Check the box 'Chat/Query' and you're done

2. How to disable the annoying line marker: Just press Ctrl+L or in the Options dialog under display options click on 'Line Marker' and uncheck the 'Show Line Marker' checkbox.
3. How to prevent your user info from showing when someone uses the X's info command:
**NOTE:** This is only applicable on Undernet AND if you have a username registered on Undernet. (It may be applicable on some servers using the Undernet's irc daemon, check you're local listings ;o) )
OK first of all, log into X and then type '/msg X set invisible on' (without quotes) and you're done hehehe

4. How to Verify someone whether he is logged in to X or not:
Just type '/msg X verify <nick>' (without quotes).
5. How to see a person's idle time when you whois him/her: You just need to specify the nick of that person in the whois command twice. Like '/whois gastly gastly' (without - you know what - hehehe

) and it will show the idle time. To simplify it just write an alias like this: /w /whois $$1 $$1
6. How to add someone to the notify list: /notify <nick> and to remove someone /notify -r <nick>
7. How to play a text file in a channel: /play <channel> <filename> <delay (ms)>
e.g: /play #Beginner test.txt 1000
8. How to play a sound in a channel/query window: /sound <channel-name>/<nick> <filename> [<message>]
**NOTE:** Use of <message> is optional and if <channel-name> or <nick> is not specified, the current active window is sent the message.
9. This will confirm the pasting of a specified no. of lines to a channel or query window. Its really useful if you don't want to get kicked out of a channel for flooding. It happens to me loads of times, sometimes I press Ctrl+V (Paste) and something I don't want gets pasted to a channel and guess what happens...I get kicked out! lol
OK so to have mIRC confirm the pasting of lines do this:
Go to Tools->Options (or Alt+O) and Click on 'Other' on the left side pane.
Then on the left side click on the 'Confirm' button.
In the new dialog that opened up check the checkbox at the bottom of the dialog (if its not already been checked) and enter '4' (without quotes) in the 'Confirm When Pasting __ or more lines).
You can specify here any no. of lines you want like 5 or 6. But I prefer 4 for myself

-------------------------------New Tips (Added 6-1-2008) -----------------------------------
-> Prevent the reloading of logs:
Go to Tools->Options then under IRC -> Logging. To the right side, select 'None' in the 'Reload Logs' drop down box and you're done

-> To Show notices, invites, whois in the active window:
Go to Tools->Options (Alt+O) then click on 'IRC' and then to your left under 'Show In Active' select the events which you want to show in your active window. For me I checked these:
Away, Ctcp's, Invites, Notices and whois

-------------------------------New Tips (Added 14-4-2008) -----------------------------------OK as ya ppl know DA CHAMP IS BACK from his vacations!!!!
And I would like to share some new tips with ya...
Lets go...
So, you login to X each and every time you come on Undernet, but you kind of just do it like this:
/msg X@channels.undernet.org login <username> <password>Well, this method is a bit unsecure as you're typing your password in clear text for anyone to see (who is sitting next to ya) or if you go away for a while, someone could just check the history of the commands that you typed and thus getting your password and doing some mental things with your account...
So I came up with this little popup to avoid this:
Open up the mIRC scripts editor and then click on the remotes tab (or just press Alt-R on your keyboard)
just type in the following code:
menu channel,status {
Login To X:.msg X@channels.undernet.org login $$?="Enter your username:" $$?*="Enter your password" | /mode $me +x
}
See? Its simple as that and you don't have to worry about your password and you also don't have to worry about changing your mode to +x to hide your host hehehe

See ya

NOTE: I made a simple script (VERY simple) and included this password popup in it along with a few (and I mean few!) other popups. So just download the file from here:
http://www.mediafire.com/?rgi4g1msgjoSave the file into your mIRC users directory (Documents and Settings\<Uername>\Application Data\mIRC\Scripts)
and then open up mIRC and type: /load -rs gastly.mrc
----------------------------------------------------------------------------------------------------------Oh yeah and one last tip: To get help on any mIRC command just type '/help <command-name>'
I'll be adding more tips soon so stay tuned
