Since when did we get online/offline buttons?

I noticed that we have little buttons next to our names telling who’s online and who’s not. When did this happen? It must have slipped by me. Anyway, I think it’s a very good idea.

Thanks.

We’ve had them for a while. They used to be check marks, but were changed with the updated version of vB (when we got all the ugly smilies, remember?) There needs to be a way to turn them off, but I guess that option’s been disabled.
