"You're". And a lowercase "w" in "welcome". ;)
"You're" because it's the grammatical correct way of saying it....
I say/write "You're"!
"You're" is the correct way of saying it :))
It's you're... if you say "your" that's incorrect.
'You're'. It irritates me when people spell it incorrectly.
"You're" is the contraction for "you are."
Whereas "your" is possesive.
