MtGox got my money too.. Around $XXX worth.. horrible that they haven't communicated back with me yet either and I PM'd MagicalTux on this forum and yet no answer. Horrible that people like this can do something like that, however I'm contacting Dwolla and hopefully others who sent their money to them through Dwolla will contact too and cancel their accounts.
Don't contact Dwolla, they can't do anything. Also, PMing MagicalTux won't work, since he never really checks his PMs.
Contact MagicalTux on IRC.
