I am very interested and willing to back it up with $$, I just need to know how the progress it coming along, and how will it deal with the release of wordpress 2.5, that is coming up in a couple of weeks, I assume WPmu will also be updated.
I'm mostly interested in the Pligg + WPmu compatibility. (not so much the forum)
Don't know if it's to late, but here are things that should be cross platform.
-Global registration.
-Global commenting (same nickname on comments on blog and pligg)
-Pligg submissions + blog posts (each submission becomes a short blog post with a link) This way, the headline in the pligg site takes reader to the user's blog, and from there to the story, that way, the user also gets some visitors.
-Pligg should remain as the main global
CMS, indexing all blog posts and pligg submissions for visitors on the index page.
-Perhaps a Pligg seniority rank, I mean, a user whose articles have been pligged the most times gets the most attention to his blog, this will also have users competing for the best spots. Could be interesting.
