I'm just starting an open source project. This question is not related to an existing project, but I want to avoid some mistakes.
I found that AGPL 3.0 could fit to my concept (copyleft, SaaSS safety, ...), but I'm a little bit curious about handling the following points:
Is it possible as project owner to sell an alternative license to customers (if needed) which does not respect the copyleft?
If so, do I need to ask all contributors to do that, or do I need to ask them before they commit?
Are there any other things I need to care about, or would it just be okay, taken to its extreme, to write something like "Use the community version which is licensed under AGPL or contact me if you need an alternative (paid) license to use this library in a closed source application"?
