If you want a new user name, do a search. http://forums.dobbersports.com/search.php (do a search by username - but it will auto-fill for you, you don't need to do the search since the user may not have posted anything)
If it is available, let me know here by responding in this thread
If your post counts on baseball and hockey didn't combine, let me know and I will combine the post count.
Any other errors with your account (not with the site, we're still ironing those out - but with your account or user name) please let me know by responding in this thread.
