Hello,
I'm fairly new to Untangle, but I have all of your free services running and configured on my network, and I even have a working VPN set up across four sites with VPN users connecting from home as well. My school disctrict would never be able to afford the level of filtering we have without Untangle, and it's the cornerstone of our recent ISP upgrade.
I absolutely love your software and I want to share it with other schools. I was wondering if I am allowed to present your software (possibly at a teacher or technology convention), or if you don't allow third parties to do presentations on your product.
Thanks for your time!
