Topic: link to profile from index & view forum?

hello. ^^; i'm brand-spankin' new to php and punbb, so please go easy on me.

i've pretty much only been doing cosmetic changes here and there and i'm getting the hang of that. but now i want to change it so that the last poster's name in the index and in view forums will link to their profile. for now i just changed it so that it would show up as another color, but i really would like it to link to their profile.

i hear i would have to change something in $result, which deals with the database, and if i messed around with it i might cause some serious damage, so i decided to come ask people who know what they're doing.

can anyone help? thanks in advance!
