Snowblizz has (as per usual) jumped in before me and done a good job of covering most of the bases
As Snowblizz said, I'm the main developer/project lead. Snowblizz is the main data file writer, software tester, suggestions/priorities man and has even been dabbling in the code base quite successfully of late. We then also have Tsudico, who is writing WarFoundry Forge (the data file creation app - until now it is all by hand with a text editor). More on the team is
here. We've also had a few other interested parties and testers, but Snowblizz and Tsudico are currently the most active.
We're definitely not a big player yet, but through good UI design, wide data file support (which is possible but not extensively written), and general customisability/extensibility combined with being open source (i.e. anyone can view the source code, edit it and make contributions back) we hope to grow and grow. I'd also say that we're facing sharks rather than whales, especially if you read the dubious claims made (which are documented on the main WF website somewhere)
See for your self how we
compare to some alternatives (completely unbiased of course, but definitely true AFAIK)
If you're just starting then you may be an ideal user, if you've got time to spare to help us. The roster creation apps are intended to help people build armies and army lists. Lots of people write them by hand (I always used to), but that involves a calculator and knowing the rules. A roster creation app isn't a complete replacement for knowing the rules, but it can definitely support you in defining your army.
Although it would help to have developers, it also helps to have users/testers who can say things like how usable the interface is, what features they need, what doesn't behave how they expect and what they think we are generally doing right/wrong. As a new gamer then I'd hope that you'd be able to say how it helps from a blank sheet compared to your first paper rosters. It isn't a guaranteed thing - we're still in the early versions and it might be more difficult, but me, Snowblizz and others are around to help
Incidentally, it was just earlier today that I was wondering if the main WarFoundry site was as accessible as it needed to be and had the right bits available for easy navigation. I'm okay with it, but I know what is there. I'll dig up the old topic or start a new one about navigation if I can't find the old one.
