geek_lover,
From the site rules link at the top of the page:
- Name change
Contact admin with your new preferred username. The site will send you a new randomized password when your name is changed, so make sure your account's email address is working, otherwise you won't be able to login after your name is changed.
You can also ask for the posts in this thread to be cleaned up to help maintain your AW to UKP anonymity but no guarantees.
I look forward to your reviews!
