Scratch

most companies aren't really that successful, there are a lot of problems with running companies through online, but it really doesn't matter, anyways companies are best off using an IMing program to chat at a faster rate and it is easier to tell whom is online, also IMing programs usually have the ability to send files so sending the most recent version doesn't have to be done through scratch, truthfully I just prefer working with one person, they would either be an artist or ideas person, but that's just me you should decide for yourself if you want a company!   

any other suggestions?
