Two projects appearing in my stats aren't running any more. How do I get rid of them from the stats list? I'm referring to the list you get by searching for your own username right at the top of the main web page (just under the row of flags).

You have crunched for the project and you have credit there that should be reflected in your total credit. If you remove the projects you also remove the credit. So you can just leave them there. If you really want to get rid of it you should change your email address on those projects as this is what keeps the accounts together.
