Hi all !
I sent an email to the webmaster of the forum to try to figure out whats going on, and the short answer is that they are working very hard on OCC 5, that's why the CVS is dead, they will update the CVS when they release OCC 5, he said that they are pretty swamped with bug fixing for paying customers and that's why it look's so silent.
There has also been the owner change that has caused some slack to.
He also said said most, maybe all of the bugs in OCC 4 are fixed (no word about new bugs ;o)
So if all this goes well, the future look's a bit brighter...
