[OMG] Are You Serious? :grin1:
Search in Go0gLe with the exact phrase "username check" (you'll find a ton of Username Checkers).

[I Thought You All Would Have Stumbled Upon It By Now]
1. Make a bunch of user names for your profiles.
2. Make a spreadsheet.
3. Put the usernames you created in one axis (1st COLUMN).
4. Other axis (Top ROW), put the sites where you want to create profiles. I use [De-lick-us, Digg, Book-Face, G0gle, Propeller, Red-Head-It, Squid doo doo, StumbLAR, etc].
5. Run a check on each username.
6. If it comes back positive, note it in the proper cell.
7. If it comes back negative on some sites, consider changing that name to something else.
8. You will find that F-book & GO0Gle will never show positive, even if the username could really be used there. They always show up as [maybe].
