I was just wondering how I can go about modifying the meta tags and how I can do any other html or php or whatever modification to my forums.
http://custom.simplemachines.org/mods/index.php?mod=1211 might work for you, and you explain more of what you want to do with html or php otherwise we can just guess.
I just wanted to modify my meta tags and put some text and a link at the bottom.
