On my RAF setup, I had a 70 and a 40 (or was it 45?) lowbie on my referrer account, and a matching lowbie on my friend account. Grouped the 70 with the friend, and ran the 70 to Strat, then summoned him with my RAF summon. Logged off my 70, got on the lowbie on my main account, and RAF summoned from my friend. I actually RAF summoned a bunch to get flightpoints, too.
