how do I change my name on here?

I signed up to Apple Support Communities quite sometime ago (2005) with my real name. I haven't used it much but have begun to find it more useful recently, but from a privacy perspective I would like to change my user name so I am not broadcasting my real name each time I ask or post something.

having looked around I see that changing my name is not something I can do, but it is something that a "host" can do - can anyone point me in direction of how I can request this?

alternatively given my limited participation history I would be happy to delete my support account and resign up for it (this time using a name I am more comfortable with) but again not exactly sure how I got about deleting the existing account so if any one can point me in direction of some instructions for that too it would be very helpful.
