Well, your forum But I think most come to forums to read peoples text rather than skim over graphics, bars, dividers and graphics
For example I usually check over a few of the sections a few times a day at work, and 2 or 3 times today i loaded the forum, thought "oh i forgot it changed to this style, oh well" and closed the browser.
Yeah, vB should work quite well on mobile devices. If you want to browse (and not post), try the archive designed for search engines. I'll also look into seeing if there's a mobile version mod that'll serve up a theme designed for mobile devices.
I like the archive view for mobile devices such as my PSP. It only lacks one vital feature: The "New Posts" link. Is there any way you could add that? Maybe not since you can't really log in with that view? Maybe that's where the mobile version mod that you spoke of might come in handy?
EDIT: well, you can login if you click the "PDA" link in the upper right hand corner. So maybe you could add a "New Posts" link after logging in?
