which variables in which hook?

Sorry, that's one small problem with using the same thread. The auto-merge makes it so that it's not obvious when you post an update.

Anyway, I only know the avatar one - I think you could use profile_updateavatar_complete. Look in file profile.php around line 3058.

I've found out that if a product contains a plugin that uses a hook that doesn't exist, it will install OK but that plugin won't ever run. So if you want to include a blog plugin with a hook that is only in vb4, it just won't be used in vb3. It's also possible to check the vb version number in your code if you find a need for that.
