Hello,
The Mingle Forum for WordPress (which you can view here: http://wordpress.org/extend/plugins/mingle-forum/ ) does not Not indexed on Google.
This is my forum: http://idanplus.tv/forumidanplus
Google crawls my site a lot, but he did not index the posts in the forum. (may be its installation problem forum).
You need to :
1. fix the problem,
2. all the posts on the forum should be indexed in Google.
Thanks!
