I can't send a support request right now, but I want to go on record how much I've hated openID using my wordpress.com account.
1) If you use http://engtech.wordpress.com and later upgrade to a domain name then you'll never be able to log in to those old accounts created with engtech.wordpress.com (openID design issue)
2) If you use http://engtech.wordpress.com as your openID then wordpress.com completely owns your logins. WordPress.com servers down on the weekend (doesn't happen often) then you're locked out of everything. If you lose your wp account for any number of reasons (ToS violations) then you're locked out of all your other accounts. (openID design issue)
3) I seem to continually have issues trying to sign into accounts with openID. I think having an upgraded domain name is the culprit. (wordpress.com issue)
This openID stuff seems like one of the worst things I've seen on the Internet lately.
