3 would be a problem. You are required to pay $25 for support of software and that is per licence. If you have 3 licences you could in effect just juggle your URLs between them and get support for all 3 but only for the price of 1. This is brought up quite a lot and the answer has been consistently the same. If you have a genuine need to swap a licence raise a ticket. The support staff don't bite.
On one persona he's staff but on the other he's a customer. Those persona's are, for all intents and purposes, unrelated. Kind of like my weekday name and my weekend name. Congratulations @Preben Madsen
I don't see the members list as an important feature. Administrators can find members through the ACP and members can find other members through the search. The members list becomes somewhat pointless once your community grows to a certain size as navigating it is tedious.
I'm not sure I made myself clear. I don't mean to rush you. I wondered if it was possible to make any donations towards your work. (If it's a free mod again the least I could do is buy you a beer. ) Looking forward to seeing Shoutbox!
