Well, in general, like Operations mentioned, only admins can change the title. There're still some people running around with custom titles though, that's because some admins just had fun changing those - why not.
Anyway, the reason we don't allow custom user titles is simple - though there's the possibility to exclude certain words from being used, people could easily get a name others see as admin and it could being abused - he could ask for other peoples passwords for example.
This might change soon though, as I'm currently looking into different hacks for this board, one of them being a stars hack. It displays between 1 and 10 stars below your user level, depending on the posts (up to 7) or moderator level (8 = mod, 9 = super mod, 10 = admin) you have. But since this board hasn't reached the final version yet, it's useless to install hacks with an update coming out every or every second week.
