[12:36am] <Homework> awesome
[12:36am] <Homework> i'll install in a few days
[12:37am] <Homework> psychon: can you look into saving partyline topics to disk so they dont disappear on restart?
[12:37am] <Homework> I'll take a look at it if I have time, but I've never poked at the partyline code before
[12:37am] <psychon> sounds... new
[12:38am] <psychon> Homework: if you want to make sure I dont forget this, open a feature request at sf.net/projects/znc
[12:38am] <psychon> it would just need a SetNV() when a topic is set and a GetNV() when a new channel is created...

Homework = me (efreak)
I'll probably take care of this myself, but im off to bed as its 12:40 am and i have school in 6 hours.
If someone else wants to do it, I would welcome it gladly.
