zanzibar: IMC is that the FIDE title for Intl Master of Composition, or as top hits in Google suggest, is it Intl Master of Correspondence Chess?http://www.google.com/search?hl=en&...

FIDE seems to suggest they award both:
See rule 0.3:
<0.32 Titles for chess composition, the judging unit being the Permanent Commission for Chess Compositions: Grandmaster of Solving (GS), International Master of Solving (IMS), FIDE Master of Solving (FMS); Grandmaster of Composing (GMC), International Master of Composing (IMC), FIDE Master of Composing (FMC); International Judge of Chess Composition (IJCC).
<0.33 Titles for correspondence chess, the judging unit being the International Correspondence Chess Federation (ICCF).>

I see the potential for confusion here, compare ICCF title and IJCC. My preference for <CG> would be to err on the side of verbosity for these lesser known titles (spell out the name with abbrev in parens).
(Note, link is to a "stale" handbook, validity expiring on June 30, 2013 - not sure where most recent rules are)
Rule 0.4 answers my earlier question about the validity of CM title:
<0.4 The titles are valid for life from the date confirmed.>
