muliple suggestions:

an option to have streaming/looping music on any pages desireable, to have the option to order topics alphabetically,oldest,most views without using the admin panel(so everyone can have it the way they want it) a personal blog system so people can have a personal bebo/myspace like page in the website, an option to have a looping video as the main picture on the site,the ability to edit a moderator so they can have limited priveledges in the admin panel,(e.g. so they could say,have the abilities to put up smiles,but not the ability to customize the icons.) a money/purchasing system using 'points',and i have one more suggestion that is currently being used on freewebs,the ability to change the cursor,but so theres a library in which each user can pick from so that there's is personalised.

sorry for the long list,but i thought that these needed to be said, and well,you chose to read them.
