I'm looking to do a forum upgrade from 3.8.1 to 3.8.3 and we have some core templating that needs updating as well.
If we can get hold of the import script then finish migrating the current gallery to the vbgallery system for numerous gallery improvements (things you guys have wanted for a long time).
Revamp of the social groups homepage and migration of regional groups to a regional groups social forums area, this will give members the ability to make their own regional groups. The social groups homepage is useless, this is going to show categories, groups, activity, etc
Some of this may require downtime but not too much, maybe 30mins or so.
