This looks great! I would totally shell out money for a premium card set - if only my professional area was represented.

Could you please create a mailing list for different professions/subject areas so potential customers could be alerted when relevant premium study sets are released?

For example, have a sign up list for people interested in accounting, one for law, one for technology exams etc. I would totally give you guys my email address so I can be alerted when relevant expert card sets are released.

As it is, I'll probably just forget about memorang.
