This has been causing confusion for years and there's been no solution because they couldn't get the domain they wanted?

They could have used wordcon.wordpress.org or sf.wordpress.org or con.wordpress.org.

I just checked and if they'd call it WordConf instead of WordCon, then they could get wordconf.org. Okay, I just registered that to stop anyone else getting it, but if they want it, I'll give to them free of charge.

Personally I like sf.wordpress.org, but whatever they use, it would be great if we could find a solution to this in time for next year.
