Several of us online – we even do raids daily. Try using a trade chat (it is a global shout) if you are looking for people. 🙂
It is some kind of safety precaution – so yeah, you can only buy and sell 999 of any given items. Don’t know exactly why, but it is like that since I can remember. 🙂
Hope to see you online soon.
It is not that you do not understand, it is that you do not even question.
