Of course @tendomart!
The idea is to bring together some implementation teams that want to do an upgrade (at least the eSaude team for now) and volunteers who can help provide extra dev power to make this happen, so we definitely want individual participants.
I appreciate you taking the initiative. Actually, see this post of mine (#15 in this thread) where I mentioned both tickets I have already created (this JIRA query) and some things that are still to-do in order to decide whether to create tickets or not.
You can either start on the already-created tickets, or else help with some of the To Dos to determine whether/how tickets should be created. For example for the ticket you created, Nicholas did his testing in November/December (I think) but Stephen says it works for METS, so either (a) it was fixed/released after Nicholas’s testing, (b) something about the esaude config is different, (c ) Nicholas just made a mistake. In this case you could try setting up a clean installation of latest OpenMRS with the SDK, and then adding this module, and seeing what happens.
