Posting comments and forum topics on all mimec.org sites is temporarily disabled. It will be re-enabled again by the end of the week. Since then posting any content will require registration. I hope it won't be a problem to anyone.
As a side note, it's amazing that anonymous content was enabled on these sites for almost a year without any significant spamming attempts. But, I guess, they weren't popular enough for the spammers to attack it, so I should probably treat the last attack as a sign of growing popularity :).
