27224 PHP SITE

I need a few modifications to my php site. The site is built upon a phpbb backend. Here are the modifications: 1) Create search engine friendly URL's and remove guest session id's (I think this is already changed, but you will need to confirm). Ideally this will be done via .htaccess. I know there is a mod out there for phpbb but I cannot install the mode because my site has had so many other modifications. If you would like to use this mod, that is okay with me...as long as it works properly. 2) Site map (database driven, display all site elements) 3) Add the ability for the administrator to change the order of topics as diplayed on the page. This can be done manually or by plugging in some logic. 4) Show forum description and topic description on two pages instead of one. Give admin ability to specify the number of words to show on each page (all words, or integer) Thanks. I look forward to working with you.
