I believe you could play the points games and if you place you can unregister from the game and your account will be credited. It may be with tournament dollars but those can be converted.
I've never heard of this ^ before (if you play a satellite with FTP's.. & 'unregister', pretty sure you just get FTP's credited to your account).
What would 'I' do? I'd play some satellites to the MiniFTOPS. Pretty sure that some of the MiniFTOPS can be bought in with FTPs. & am guessing there'd be some sattys for them too. I typically play something like the SNG Satellites, where top2 win the prize & 3rd gets back a bit more than the buyin (in FTPs). Or as 'Crummy' mentioned, "get a shirt".
edit - I guess the MiniFTOPS doesn't have direct buyin with FTPs anymore (they used to have it so you could reg. for some of them with FTPs).
