You have a forum for them here: http://xenforo.com/community/forums/development-tutorials.80/
Your staff posts to one but not the other on certain occasions.
Was looking for this thread: http://xenforo.com/community/threads/database-schema-differences.22621/
It was not in the Resource manager.
Furthermore it is simply confusing to have a forum dedicated to Development Tutorials and a Resource category dedicated to them. Consolidation of that top forum might help?
