Sigh...
There was another side effect of the server failure last weekend, which was not discovered until a few hours ago: There were no emails sent. Especially stupid if you just want to sign up here and get an activation link.

To all whom it may concern: The activation email has been sent to you again.

Unfortunately, no automatic event emails, contact requests and similar have been sent. Reconstruction would be much more difficult and I hope everything works without those emails ... otherwise just ask if anything is unclear. thnx.
