Edtulane 101: say "wb" and then leave and rejoin

I’m pretty sure some of you staff members already know about the fact that I am paranoid about being seen. One time, someone just connected, I said “wb”, and then had to leave and soon rejoin becuse I’m paranoid about being seen. After rejoining @spiderroom said “edtulane 101: say “wb” and then leave and rejoin”
