Thanks for the continuing feedback on this subject.
On reflection, we (the moderators) think that the main emphasis needs to be on the post being logical and legible. It IS important for us all to make our posts as easy to read as possible, but typos, grammar and spelling are a lesser issue (unless they make the post hard to read). With that in mind, we have amended the Posting Guidelines accordingly.
As always, tolerance of others should be key. We don't want to impose a bunch of "rules" here (one of the reasons we call them "Guidelines"

. Also, don't let yourself get mad, you can always ignore a Member's posts if their style really bothers you.
Any further feedback is welcome!
