my experience with other php sites like this is that the admins absolutely hate doing a username change, as it entails all kinds of monkeying with the forum database, the gallery database, the market database, the freebies database, etc. ad infinitum. so it's an opportunity for somebody to write an app that automates this, rather than forcing the admins to do it manually. if they are gonna ask nic to write such an app, they gotta pay him. my estimate would be 40 hours at $40 per hour.
