I recently joined about a few days ago from facebook, and accumulated 525~ points, on my facebook/gridrepblic sites, the points are frequently updated, but the g-hours are still at 0. When my screen saver loads it says I have 126 G-hours. Do you know what the problem is?
There can be a bit of a delay at times between the stats reported on your desktop and those at the GridRepublic or Progress Thru Processors websites. What you see locally should be the most up to date because it comes directly from the project servers when you finish work units.
The stats at Facebook, however, tend to lag a little. Stats servers collect data every day from project servers, and Facebook collects data every day from the stats servers. For this reason, there could be a day or two of delay before your stats make their way to Facebook.
I see you now have some credit at the stats servers, so it shouldn't be long before Facebook is reporting this, too.
