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.
My recommendation will be to clean slate everything for pull requests. Pull requests going forward will need to be under the new unified contributor license agreement (there is a single CLA for all open source at Sangoma, meaning you sign it once and you can contribute to either Asterisk or FreePBX without signing again, and it is instantly accepted).
