I think you're out of your mind if you are going to offer 24/7 text support when you actually have nothing to support. You said that you do this as a hobby, and that you don't actually sell any services.

So what are you offering support for? The use of vBulletin? You're going to highly regret it. People will abuse it to become more "buddy buddy" with you, you'll obviously get messages at all hours of the night, it would pretty much eliminate any purpose of having a PM inbox.. which is a feature you paid for when buying vBulletin.

I think it's stupid. You don't need to devote your entire life to a hobby forum. Even if it was a business, you don't need to devote your life to it. You need spare time, get out with friends.. socialize. Don't spend your life on the computer, you'll regret it in record time.

I guess it's not really tech support, but more of a chat room for me really. I just thought some people could use it as tech support. Besides, even though its 24/7, I set my phone to alarm only when I sleep, so nobody is going to wake up.

isn't called Twitter?

I don't want to bother with twitter though.
