What browser are you using? The major ones have spell check. It's not computer dependent. And for that matter, why is your grammar bad? It it that hard to remember to hold down SHIFT for the first letter of a sentence or to add the occasional comma?
As for your bump on that thread, that had already been established. If you bump a thread to add new information or content, that's fine, but if you just repeat info already stated, you get into scary-scary time. Oh, and your grammar needs improvement. This isn't a chat room.
