Our association is looking to purchase some new software for use in scheduling and assigning referees. Also, we want each official to be able to access this software to enter personal information and enter the available and booked nights they might or might not have.

Any suggestions as to where I may find some good software?

It really depends on how much money you want to spend. But it sounds like you're going to want a web based application for sure. So then you'll also have to worry about things like hosting. A good place to start would be your own association and see if anyone has any experience with this kind of thing. It's not really hard to put together. Or you could try contacting somebody at stripezone (www.stripezone.com) or another place that already does what your asking and hosts it themselves. However I have no idea what they charge for a season. In the other thread about software someone posted a link for their program that did about what your asking. There's tons of stuff out there, try google.

My association started using Arbiter this year and we really like it. We use it for scholastic and rec ball.

Or, if you want to spend 1/10 the money and still have all the power . . .
