I released an updated server version tonight (Dec 3, 2007).
The purpose of this update is to modify some logging to catch errors a little better. It is still a beta, right? There are still some minor bugs I'm working out, hopefully this helps diagnose them.
[update]
Ok, there was a small problem. I'm using MS-SQL server as the back end database in WebMarkers. It sort of choked. It's back now, no data loss or anything... (it's backed up religiously).
I'm thinking more and more of switching to Postgres.
