Though this is somehow annoying, of course, I wouldn't immediately suspect the worst in the first place ...
I remember very well, when we've had that issue on the MOUL forums for a few weeks, that was really a bit tiresome lol, but I don't remember what caused the issue, only that we had to delete our board cookies, which didn't resolve it for all of us immediately though ...
Ok, however, as no one said sth by now I suppose that you might be the only one, but nevertheless I wonder if this issue is server or client related, and I also wonder if what you suspect could be recognized or detected somehow by Adam or others with access to the server or if anyone of the knowledgeable folks here have any other idea ... Yeah, that's all that comes to my mind right now ... Good luck, Annabelle, and I wish you a soonish proper and convenient access here again ...
Edit: I just looked into my profile and saw that you could easily change your password ... you'd have to enter your old one again and maybe had to go through the captcha test once again, but maybe that could resolve it ... at least you would have done everything on your part ...
