How do you say you won't be around for a while?

(1/2) I would like you all to greet a friend of mine. He will be taking care of my blog for about a week while I am traveling. Now, this friend will be hard to notice because he does not say much.

Or do much.

Nevertheless, feel free to greet him. His name is Atus.

Just drop by from time to time and say, "Hi, Atus."

Yeah, dumb joke. Deal with it :-)
