Unfortunately, I had to take down the forum after it had been severly hacked and spammed over that last days.
While this is unfortunate on one side I am not too unhappy about it either because the forum software I was using did just not get their security issues under control. That meant a lot of administrative work for me cleaning up the messes spammers were causing.
Please use the JIRA tracker for now to submit your support requests. I am looking into creating a new forum if I find a suitable software for it.
