Collaborative

Hello,

I have problems to access the Collaborative in the last time. I'm not sure whether it's my problem
(my DSL-Router has an opened port 5910) or the Collaborative has limitations in the number of concurrent users.
I would appreciate any suggestions.

Should I emtpy the *cache' dirs from time to time (without deleting  *.c3d files) ?

Greetings,

Marc
