Well we have 8 developers - Richie, Ricardo, Erwin, Matt, Ben, Uwe, Stian and I, all part time, and a few hangers on who do different things.
E.g. Our resident artist Chris who does all our Ninjas. (and we did the fund raising recently to help his mum out), Mark who helps with templates, provides us with hosting and does our system work for us, and Igor who joined us from last month and is working on Docs for us.
There are others like Steve who are working on New Ninja sites as well.
The goal for most of us is to work full time eventually. But money isn't flowing enough just yet. But I hope to make a couple of people full time in the next couple of months.
@Download system extension for users
It will and it won't be available :p
The client side extension will be available and I can guarantee you that every member is going to want it. ;)
The master component though won't be public. By the time it's done I will have invested close to 10k into it, much of it my own money and not from Ninjoomla, so I won't be handing it out too quickly.
It's also not really something most people will want on their own sites anyway unless you sell joomla extensions.
