Hey dude. Try to wait at least 2 weeks minimum before thinking about replacing somebody. Also, I'm afraid I'll be too busy to ref anything at an adequate pace with my next semester starting soon, sorry Try posting the match in the ref queue and someone will pick it up.

Hey Char,

I messaged somebody I'm in a match with that our ref hasn't been online to ref our match in like... 2 weeks almost.

If he wants to continue and you aren't too terribly busy with anything, do you mind taking it over for us?

I'll link you to the match and whatnot if you'd like, I just wanted to ask if you were available before I did.
