34870 Install opensource scripts

For each of the topics below I need you to find the best/most sophisticated opensource script (php/mysql) in terms of functionality and flexibility. If I agree this is the right script after viewing the demos online - then I may need you to modify the output colors/format to fit what I am looking for/integrate to a design template. All of these opensource scripts must have an admin funcitonality! 1. A solid FAQ script 2. A Forum script - need to be able to create as many separate forums as needed ([login to view URL] different topics) 3. A polling/survey script (must be able to insert a poll or survey anywhere in the site - controlled by admin, showresults, prevent multi-voting abuse etc...) 4. Event calendar (2 views: calendar and text listings - must be able to categorize the events)
