tec trouble 
start of entry was not available for some hours during the last days. First it crashed with a java error, forcing me to reboot the machine. Then I got spammed, so I decided to deny registration of users. So if you want to add something, you still may use the guest account or send a mail to me for retrieving an user account. Finally the dynamic dns updater was not doing its job…
Now everything should be fine again. Have a nice weekend!
