I'm currently the active maintainer of a free Symfony bundle, the purpose of which is to provide an out-of-the-box messaging system for use with FOSUserBundle (a popular user system by the same team).

I was handed the reigns after my fork porting the project across to Symfony 4 was recognised by one of the team members, he reached out to me, offering me the reigns as he did not have time to maintain it himself.

Since then I've removed support for Symfony2.8 (as Symfony4 support makes compatibility with this version impossible), tidied up relevant issues, repaired the CI pipeline and resolved all outstanding pull requests.

I hope to be able to do more with this bundle as time goes on and have some great ideas for additions!
