Non CMS / Affiliate Management Scripts Inside A Members Area

Just wondered what other types of scripts you folks were using inside your members areas at the moment?

Right now we have a message board and, next week when i update the members area layout im going to be installing a poll feature that will update every week with a new poll question (to help me get feedback from current members and demographic data for market research) im also thinking about adding some kind of ecard script or freemail script to the members area as an added bonus content wise although, nothing has been finalized on that last one yet.

So, other than your CMS backend and any affiliate tracking, what other scripts are you currently (or thinking of running) inside your members areas?

Regards,
