It's all free thanks to the generous support of our sponsors (http://batsa.us/sponsor.shtml), but they do not influence our content - see our mission statement (http://batsa.us/mission.shtml)). But that also means we depend greatly on the time/effort of volunteers. Regardless of what level of industry expertise you have, if you want to help us take it to the next level, we highly encourage you to learn about the various ways you can get involved, either as a volunteer (http://batsa.us/volunteer.shtml) or a cash or in-kind co-sponsor (http://batsa.us/sponsor.shtml). You will benefit from being involved with this dynamic community of hundreds (so far!) of local, forward-thinking sourcers.
