I believe it's silly to expect perfect grammar or spelling on a discussion board.
Gotta disagree here, Robert (or should I call you Rob? LOL) To me, letting spelling errors and obvious misprints is a sign of laziness. It's like the writer that's too lazy to capitalize, punctuate and write in paragraphs, they just ramble on in incoherent sentences all jumbled together.
That little red squiggly line under a word means something, investigate and learn.
p.s., A handy little browser add on that installs an icon in your toolbar that looks like a dictionary--free here. Highlight a word and it tells you not only how to spell it but what it means and the proper context in which to use it.
FWIW, IMO, the presentation of one's thought is directly qualified by the effort to communicate it properly. :-)
