Pull or merge request
I'm really sorry but wpForo is not opened for pulling or merge. We'll open it with 2.0.0 version. At the moment you should create a separate plugin and connect all features and functions using wpForo hooks. If you need some extra hook please let us know, we'll add it in next version so you can add it in your plugin and modify wpForo core too.
In case you want to say thank you !)
We'd really appreciate and be thankful if you leave a good review on plugin page. This is the best way to say thank you to this project and support team.
