All I've found for CHTH are:
1. Chemotherapy
2. Christian Thought and History
3. Yet another acronymn -- CIMMYT (some kind of international center in Spanish)
Alright, Mister, you've already used 2 acronyms here -- one more, and I think the SHLP (Short-Hand Language Police) are going to have to escort you out of this thread!
Except... I just realized I've used 2 acronyms in this post (and more, if you count my trying to explain YOUR acronym.)
D'oh!!! (Not quite an acronym, but maybe close enough?)
Looks like I'm going to have to SMO (See Myself Out.)
