There are several problems currently active. They are summarized
here. A common one is the time-out problem. I did some testing this morning at 7am (german summer time) and had no problems.
The other problems have to do with problems caused by the server works we had lately. Since technical staff is very limited (and afaik she is on vacation right now) it takes some time to repair them.
I don't understand why people always think DMOZ will have no future because of this problems? Technical problems are domething that can be solved. The future is determined by the amount of active editors - and at least in the german section we never had so many very active editors as today.
