Well we've worked hard to bring you a standards compliant portal with 2.0 features.  This is the pre-compiled version of Alpha 3.0 that is really easy to install and does not require VS 2005.  Just change your connection string in web.config and configure IIS then youre set.  Please go get this from novell and test.  We really need to know issues so post them here:

Things to note:

This is still alpha [but at the end of it].
HttpCompression is on by default and gives better performance but we do not check
if browsers can handle compression [ in final we will].
The version number reads 1.0.0.0 for some reason and if you know why tell me :).

A full source developer preview will follow this release.  Im going to go take in dinner first :).
