The point, which I've made several times previously, is more that there are few sites that are on par with this one, in the .NET space, especially for certification. I can't really think of any that I highly recommend - techexams.net is the most prominent MS exam site I've seen, but their developer board is all but dead.
You might try Usenet instead, since there seems to be more discussion about Microsoft certifications there.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
