What extra functionality is needed on this site?
There's a hell of a lot here to read, within only a matter of days. I think we need some summary views, statistics, opinion polls and such. What do you need to see? It's interesting to read through people posts and comments, but can quickly get tiring, especially if you're looking for specific information.
Some initial ideas of mine - they may not be good ones, but are all technically feasible:
Opinion polls - What topics (and what questions)?
Summary views and statistics - E.g. how many users here, how much total money lost, average amount lost. Maybe even a geographical breakdown, breakdown by nationality, etc.
Files - Ability to upload documents?
Structure of forums - What topics and sub-topics? Anything missing? (maybe an "emotional support" topic, and probably one for this topic, i.e. site features.)
