Every so often I'll receive a Steam friend request from a user whose name I don't recognize.
I don't want to deny the request, since they may be trying to contact me for completely legitimate reasons. (Item trading, mutual friend, etc.)
Steam doesn't allow messaging users who aren't on your friend list, so I end up having to accept their request just so I can ask them why they friended me.
Is there a way to message a user on Steam without accepting their friend request?
