I couldnt thank you enough for the info. Searching for mod_rewrite on phpbb and google for some reason gave me substandard results at best, able2know SEO looks absolutely great!
Atachment mod I guess I'll install. My main concern was with my server holding up with attachments, but thinking about it wont make the slightest bit of difference. Bantrol, if you say its good, I'll install it to at least check it out.
