Well, this forum is a respectable forum and should be treated with respect in the form of good grammar.

Well sir, I am sad to inform you that there is a grammatical error in your post. I will correct it in red for you so you may be better educated next time.
Yours sincerely,

OR

This forum is a respectable forum. This Forum should be treated with respect in the form of proper grammar.

Why is "Forum" capitalized? Aren't you using it as a regular noun? Not a proper noun? You aren't using it such as a name like "Anarchy Forums". You're using it as "Hey, let's go use this forums." Or something similar to that.
