"Read the Friendly Manual"  (plus variations on the "F" word); "For what
it's worth"  - also, HTH= "hope this helps" which appears a lot

I don't think abbreviations is worth mentioning in the FAQ.  These seem
to be general email or internet abbreviations.

Just out of curiosity: What do "RTFM" and "FWIW" stand for? Should we
have a
