Playground: Can't register

Tried to register on Playground to share libraries I've written for the real-time clock, multiplexers, and a TTL-based data probe, but all I see is:

( : registerform : )

(Spaces added to prevent smilification )

Can anyone help with this?

Your registration on the Forum should be good for all Arduino sections... also the Playground.

Thank you, Msquare... for some strange reason :~ , I was thrown off by "Unfortunately for the moment we are unable to use your same username and password from the Arduino Forum" which currently appears on the Arduino Playground - Participate page. Maybe I'll see if I can edit that!
