Disabled Posting for Guests

[Ingo Mierswa]

Hi all,

I just wanted to let you know that we unfortunately had to disable the posting by guests since the number of spam posts increased too much during the last weeks. We also changed the "captcha" system, i.e. the "please type in the following letters" - system during registration and hopefully we will get less spam posts in future.

All the best,
Ingo
