22486 A call for all PHP scripts

I have a website that is getting great traffic, and I want to add as many features and services as possible for our users. Please contact me with as many ideas as possible for web-based activities (youth activities such as Confessions, Votes, Groups, Chat, Email synch etc, along with Parent type applications - Calendars/Schedule, Email synch, Contact lists etc). I will consider anything, from straight-ahead, to downright weird (except Instant Messaging - we already have that covered), as I have a decent budget to buy a lot of scripts. Thanks!
