May well be true, but he didn't ask what he meant by "linked in my signature" just fired off with a "thanks for nothing" needless post. At that point Northman had the link, but chose to come in to tell M3ntir he did wrong by him.
Besides, I think if you can figure out how to @ someone on this forum, especially with the first part being "the" you should be able to use the search function, or just ask "what is search?" or "what is signature?", one of us would have told him.
The attitude came in when Northman already had the link, and chose to make a post about how M3ntir should have been better.
