Justin replied on the thread about the forum problems but I can't reply to that thread either, same error
I originally tried to reply to Andy's forum post about 5 hours ago, that seems like a lot of time to wait, if it is in fact a server problem and not some bug in the forum code.
I've posted the DNS SRV issue on the mailing list
This post got blocked by a different error, telling me I can only make one post every 3600 seconds. That seems like a very overzealous spam filter.
Are you familiar with IRC? You can jump on #hornetq on freenode and chat with someone if the forum isn't adequate.
