Thanks for the welcome.
I thought of Slack although I do not prefer it I guess it is the most practical solution in quick (casual) aligment - thanks.
My questions at this point essentially hover around understanding the project big picture - its architecture and what it does facilitates (or what it could). Of course I saw the map & features which are a good start but as soon as I dived in the code I felt the need of better map to understand the components /modules, their individual goals and functions which should be the start before understanding what and how to improve. It perhaps could also play a role in helping people understand what they could do / what solutions can be put in place or how far from what they envisioned this software is.
I stop my mumbling here - let me know if I can be of any particular help (everyday work with js, python and advanced gnu linux user) otherwise I ll keep my general wandering throughout the project.
