Well, Jon, yeah, we should all be better at that. True, spell checking software is not a panacea, and despite cautions, we still make mistakes.
Still, the spell-check function has kept me from looking like a COMPLETE fool more than once, and I do miss it here.
That said, I have a workaround.
Before you post, cut and paste your response into a Word document, and use the spell checking function there. After it's checked, cut and paste it from the Word document back into the response and post.
