Went to post to the sf.net bug tracker, spent some time trying to log in,
finely got to the bottom of it:
ctsai-sf: CarlFK: OpenID support hasn't been completely removed (yet),
however it is something we're considering. In the meantime, you can still
login using an OpenID by using this special login name:
https://sourceforge.net/account/login.php?openid
(03:47:03 PM) ctsai-sf: CarlFK: To be more accurate, it's not being
"removed" but rather, we are planning to re-write our authentication/login
system in the near future, and we're determining if it's worth the effort
to re-implement generic OpenID support.
if requested I'll figure out how to login to SF.
