I am currently running an online league using a different software. Is there any way to get this league converted over to use DDS?

Well its possible depending on how much work you're willing to do in setting up files and how much historical data you can pull out of the other game in some kind of usable format. If you wish to discuss contact us using the support form on our website and we can discuss what it might take

I'd be interested in this also. We are looking for a new game, we would be willing to start over, but would love to be able to bring the players over.

Again its possible depending on how much work you want to do with the databases and what you can pull out from whatever you are using now. If you contact me via email or PM we can discuss what is possible and you could decide how much work would be worth doing
