Is it possible to delete my account and posts?

you can close your account which will remove all personally identifying details from the account information.

However you cannot have your posts deleted as these are part of an ongoing discussion and may result in gaps where a topic changes or a user responds to something you have posted. also what about posters that quote your post? should we delete those too?

if there is a particular post that you feel would compromise your privacy in some way then admins and staff will do our best to help you but a blanket removal is not an option.

edit: dammit Zaph, i was eating a sandwich! I would have hit reply sooner...
