What is the rush? Not like there is no Bitcointalk available? Forum is here and up and running.
It is a matter of new features for both conveniency and enhaced security.
Also not that there aren't any users on here as it is... Over 1.3 million accounts and counting.
That's not the basis. Also, we should count unique users from those 1.3 million accounts.
I rather they take their time and make sure it works well, and it's secure, work is progressing on GitHub so not that they are not working on it either.
If you had read above, you should know by now the concerns that will rise up when they take too much time to accomplish the new forum.
Give time to time, a forum with so many users can't just be switched over just like that.
Migrating the accounts and details are another thing. As far as I know, they're still developing the website itself.
