Alright. On the level gifting front!

Recruit-A-Friend trial characters (continuing even after upgraded) will receive 1 free level for every 2 levels gained up until 70. This means, a "trial" character may successfully give away 35 levels. These levels may be stored up to 90 days, when the Recruit-A-Friend benefits expire.

With this, you may give all 35 levels away at once—all to one character, or to multiple different characters. A character may receive gifted levels up to level 60.

Hope that helps.
