I don't agree to andy32.
The staff of the site don't have to be visible, to help and solve problems and to answer questions. They will do their "job" as soon as possible, no matter if there is a online status or not. If you don't have the time to wait for answers, or solutions, you should think of paying for the support ( and I don't mean an irregular amount of donation! ).
At the moment, the site is totally free for all users and I am very thankful for all the free services, that all the members of the staff are giving to us! :cheers:
It isn't necessary for anybody to know the online status… in fact I think, it should be a user choice, if they want to be seen as online or not, but I can very well live with it, that there isn't such status.
