[AP] Additional User Onboarding Tasks 2.0.1

[benFF]

If you are still working on this, it would be awesome if the "User has posted in the following category" could be changed to "User has posted at least X times in the following category".

I'm using advanced criteria with ThemeHouse's Extended User Criteria to achieve this at the moment, but this does mean there's an evil extra database call on every page load
