SSO now working on forumdev
The single sign-on code is now added on forumdev.typo3.org so that people should be able to log in using their typo3.org users.
Logins can be made using the pretty popup form located in the main nav.
Some details about what to expect from the SSO:
If there are any posts from your email in the newsgroups/forum, it should match your typo3 account to the forum account based on the email. If you update something like your name in typo3.org, the next time you should log in it should update that in the forum as well. Passwords -- like with all typo3 SSO implementations -- are not stored in the forum's database, only on typo3.org.
Of course, feel free to test and raise issues,
