I wish I could find a good catalog of types of deponent verbs still (though I found one interesting paper by a guy arguing against the term deponent which actually does give an okay list of types but doesn't help explain the implications of principal parts of each type).
EDIT: I wish I were hitting this person who is clearly just choosing to put aside the term "deponent" (Latin speakers snicker here) in an attempt to display animosity towards what he perceives to be ignorance (which is in truth a traditional borrowing of a Latin term in discussing Greek, a practice which was used regularly in Classics for centuries!)... reality is what it is... you don't have to beat me or anyone else over the head because you "figured out" that the Greek deponents did not put aside their missing forms but perhaps were never conceived of having them.
