Microsoft just announced the CTP release of a offline client for MSDN Forums. The client provides just read only access for now, but posting will be also implemented in future. This is much anticipated tool that the MVP community has been requesting for years, so it is good that it is finally alive.

You can download it here: MSDN Forums Client.

It requires that you have also installed Windows Live ID Client SDK, SQL CE 3.5 and .NET 3.5.
