If your issue affects only a single driver, it should be reported to the driver itself. Any other issues in the Mink abstraction layer and feature requests should be reported to the main Mink repository.
Contributions should be sent using GitHub pull requests.
Any contribution should be covered by tests to be accepted. Changes impacting drivers should include tests in the common driver testsuite to ensure consistency between implementations.
New features should always be contributed to the main Mink repository first. Features submitted only to a single driver without being part of the Mink abstraction won't be accepted.
