First, I'd like to introduce myself: I am Yair, and I'm handling, and will handle development in DF.
The new DF portal had some login issues. I want to thank IronMan for notifying us about this problem. It took us some time to find a suitable solution for this problem. Yet, we're smart guys around here. A new patch was issued today, and I think it solved the problem.
For all of you that had login / any other technical problems, please report using this link:
