Itchy: If you wish to spend as much time writing what ought to be a quick paragraph for a forum as you would for a paragraph in your doctoral thesis, be my guest.
If it takes that much extra time to get proper spelling, punctuation, and grammar in a short paragraph, you need to go back to school, because your English skills are hurting you in other areas of your life.
As a commercial for an English course once said, “People judge you by how you speak.” The same can be said about how you write.
