No progress, no. Just trying to get a regular release out the door. YAF.NET still has bigger fish to fry: getting the database layer under control... but I've made big strides in that regard.
As with all things: you are welcome to assist. My time for YAF.NET is very limited. Taking the other libraries (YAF.Core, YAF.Types, etc) and just tossing the existing YAF web form library, you could pretty quickly have something workable.
