I can assure you, it is a completely legit program. Everybody on the team with the exception of 2 or 3 use it. It's just an easier way to communicate and it is completely free provided you don't spend your 5 free phone minutes and then continue calling people on phones.
We are almost done recruiting. We just need experienced concept artists, animators and programmers. We currently have a staff of 10, including professional foley artist Stephen Muir and we're hoping to have around 20-25 people maximum so that when the project is completed, you get the most money possible. A larger team also guarantees that the project will get done.
