Just a small update as I am sure many are wondering and DF seems to be lagging behind on the comments

SourceOP is currently in development. 'Some' work is being done on it but since Half-Life 2's plugin system does not currently allow for much to be done, progress is very slow. The main slowdown in the progress of SourceOP is waiting for Valve to release updates and new features on the plugin system. Until then, you will not see SourceOP progress much.

DF is thinking about releasing a alpha version of SourceOP. This version would have the simple admin commands such as:

admin_ban admin_slay admin_kick admin_map

and would also have some commands to control the physics somewhat. I think DF also has a working credit system in, but with nothing to buy as of yet.
