hey...out of curiosity...could you setup an index.html with say...a large disclaimer...and have a cookie system so that if they'd already visited and agreed to the disclaimer...automatically move them to the index.php the next time they visited the site?

wait...i think i just realized my mistake...so while my suggestion may or may not work...now i'm confusing myself...the commenting would actually appear in the profile...perhaps...cause for a moment there i was confused and thought that it'd basically result in the exact same thing as a pm...which was why i was about to propose using a shoutbox system...and then realized my mistake in thinking that i'd made a mistake...so i'll shut up

ps...beer and t3's at 7:30...not as good an idea as i thought...

maybe it's my ignorance to coding...or the pint of beer i'm having at 7:30am along with the wonders of a T3...but couldn't you make a module specifically for commenting...and...add the mod to the template? so that it'd be something like (now a reminder of the beer and no...i repeat no coding skills):

module containing:
-commenting stuffs
-it's own members table to follow along side regular members table with user id
-some dozaks and whowhits

edit profile template with:
-whatever profile you're looking at = commenting user id thingy
-call up commenting module thingy
-enjoy and celebrate with another pint of beer and a T3

*shrugs* i'd been looking for something like this for a while...and just got fed up...and one day stumbled across RadioBlog and just kinda...used that as a block...and gave members permision to see it...then i used a simple upload script for users to upload their own songs and limited the extentions to mp3 and rbs (since that's the format that RadioBlog uses)...the only downsides is that...well...it's not a mod...and it has the radioblog button thingy...but yeah
