Found occasionally the ancient post. Right now I make a new version. It will be mostly based on Yet Another Forum 1.9.3. Unfortunately, I can make it when they make a release. The foeums will have fully compatable data layers. That was not a case with VZ-Forum first version. Moreover, I make PostgreSQL datalayer too. It will be available in February.
Before that I can't make a full release, to keep up licence compatability. I experience some problems with MySQL 5.1 compatability now too.
I guess that ijn February I would make a new realese base on mojoportal-core. It's a difficult task - I forced to change a lot of code, as YAF developers made their product fit perfectly with MS SQL only.
Let's hope that they make some steps to fit it in , as I've published data layer and conversion tips in a separate sourceforge project for their project. I think that by spring the mojoportal will have full featured extra module with Postgre and MySQL support. And of course Mono.
