I have a member who I think accidently signed up three times. How do I delete two of the accounts while keeping the third?

You'll need to know what the names of those other two accounts are, and then go to your 'Administration Panel' then go to 'Edit a member' then put their name in the text field provided and submit it. That will bring up their 'profile page' where you can delete the account. You'll see a "Remove This User" link at the bottom of their profile page, just click that and repeat the process for all accounts you want deleted.

Good luck!

Thanks for the help!
