Things that acquire assets over time, and which don't require you to actively play very much:

    - Rest Experience       (requires you to log in every 10 days and claim the experience.  Result:
                             0.75 levels free experience, or 0.075 levels/day free)

    - Mooncloth             (log in every four days, buy/farm 2 felcloth, and post it on the AH.
                              Result: 15G+, or 3.75G/day)

                             [note: in terms of creating new characters soley for this...  someone
                             said it requires a lvl35 player, at a minimum to get to tailoring lvl 250)



Again, some of these may seem kind of low, but in many cases, they're basically free, so
