Posting of new topics works now - wasn't tested the last time.
Thanks to FastestCoderOnEarth to letting us know he couldn't make a new topic.
As said earlier, the forum works with the new login at the url below:

With the existing login @ https://www.rankk.org/index.py, you can only view but not make posts in the fourm.
