I've been really frustrated with the GotDotNet workspaces. They've been down, AFAIK since last Thursday. For the WSMQ project, this couldn't have happened at a worse time, since Yahoo just launched a similar product last week. Really, I've been frustrated with the reliability since I've started working with it. It's a cool site, especially the Source Control stuff, but horribly broken. Scott Hansleman posts about the same problem.
So, I'm going to close the WSMQ Workspace (as soon as it comes back up), and am moving the project to a dedicated site. For now, you can download WSMQ from the link on this blog. Stay tuned.
