yes, by Athena's pubic mustache, Rich Taff is right !! Scotty didn't misspell anything, he was (quite possibly unknowingly) just referring to that complete stranger of a user's own welcome, saying "your welcome", like if I start a thread, and someone would tell me "your thread".
I'd like it if...nay, DEMAND jrZiniewski replies to Scotty saying, "yes, my welcome" to validate this...ever so important endeavor.
