If you nitpick about someone's spelling or punctuation, you leave yourself wide open. So, Vic, who are YOU blaming for ending your post with a comma?

Neither you nor Jim deserve picking up for spelling, grammar and typos. If I get picked up, I often succumb to the temptation to go for the jugular of the nitpicker, which is generally very easy. Jim types fast and types a lot. If you can understand what he's saying, just leave it. Right?
