Thanks for the replies guys :_) I always like to hear what people think... just a shame that some of my stuff seems to get unnoticed due to other scripts :\
Slub77: No idea what you're talking about, sorry.
Sunslayer: yes, I know I can declare multiple variables on a line, but I prefer not to, it reads easier for me this way :_) No idea why the percentage is cut in half, you could try changing line 4 to:
window -dak0p @opchart -1 -1 280 290
BlueThen: good idea! :_) I might actually do that, throw it up on my site.
FordLawnmower: meh, no problem, I'll leave it here, at least it has some substance :p
Jethro: Yup, because as we all know, IRC is SERIOUS BUSINESS!!!!!111 ;_)
