I know this isnt much but i wrote it to use on a friend because i could never catch up with him when he logged into my channel, and i found it very handy for other people i couldnt connect with. I know it is small but i believe it is usefull.. Udate: Some changes have been made so u can keep it loaded after it has been used instead of having to unload it each time. Just go to the channel u want to use this in and right click in your channel window and goto Msg To User then click on add channel. Be sure your in the channel u want to use it in because when you click add channel what ever channel your in thats the one it will add and use. you can add more than one channel also, for the second one just goto it and click add channel. it will automatically turn it's self off once the right user has join the channel and gets the msg. It will also unset the last users name and msg once it is read. Another update: Added a line so you can check and see if u have a msg pending or not. Click on Check Nick And Msg that will make it easier than going into remotes to check it.
