Hey there,I am not one of the developers, but guess I am definitely experienced enough to answer (some of) your question and I will point the developers to this discussion so that they can reply here too or get in contact with via private messages.Let me start with a short comment regarding the plugins: Yes, the plugins feature is still in development.1) The github repo https://github.com/osTicket/osTicket-1.8 contains both, 1.8.x and 1.9.x. The branch "develop" is 1.8.x and "develop-next" is the current 1.9.x - so when you like to do some pull requests, I suggest to make them within the "develop-next" branch.2) Documentation is lacking a bit - sure there are some comments in the source code, but a detailed documentation how you may expect it, is not there. Besides that, since plugins are not yet fully implemented, there is no documentation on that since it's not finished.3) You can communicate in so many ways with the devs, e.g. thru email or phone (mentioned on there website: http://osticket.com/contact-us), or regarding pull requests or issues via github or here at the forum - I guess that is open to you and the devs how you communicate ;)4) I leave that question open to be answered by the developers.Btw. the developers are Peter (protich) and Jared (greezybacon), so when one of them contacts you, that you know these are the devs ;)Cheers,Michael
