It's been bugging me for some time that you cannot subscribe to a social group and receive email messages when new topics are posted. This is particularly bad for the invite-only social groups that have few, but important posts.
It has come to my attention that this feature existed in vBulletin 3.8.0 but was broken. It was removed in vBulletin 3.8.1 (which we have now) and readded (and fixed) in vBulletin 3.8.2
Can we get a vBulletin upgrade to a later release? I think 3.8.5
is the latest 3.8 version, released in March. vBulletin 4.0.3
is also out, but may have breaking changes with OCR's backend.
