Do you know PHP?
Do you want to be “that guy” (gal)?
Do you have a github?
As they slowly push things to github there is a cool feature to see all open pull requests for FreePBX. I encourage people to start doing code reviews. If you want to get in to development this may also be a good way to learn the plumbing of FreePBX.
There were ways to do this on Bitbucket but Atlassian products are . In any case much of what is there now is contributed and I don’t know how they are going to handle those. In any case I think it may be good for the project to have more people helping vet the code.
