Ok, honestly I have NOT read every page and post, but most of them until page six...so I consider that qualified to make a comment.
When I post in a thread that I have not followed, at least somewhat. from the beginning I read the first post thoroughly, then skim the next few pages and usually end up reading the entire last couple pages of the thread. Then if so inclined to comment I do. And I am guilty of saying "have no read all of this, but _____________________." LOL
