We exchanged a few emails between developers since I arrived, but I believe a mailing list would be better (at least for developers, forums are probably better for users):
1) We don't need to know everybody, all registered people will receive mail
2) We will have access to mailing-list archive (much better than forums in the long term)
3) It will be easier to submit patches (for instance with git-send-email), when people are not comfortable enough to access directly a git branch, or just want an advice on a possible gir patch. The current forums format does not allow clean posting in text mode (important for patches, where every space is important).
4) No need to be on-line to view messages (if already received) or to reply (they will be sent later).
Tuxfamily offers mailing-lists management I think:
https://faq.tuxfamily.org/MailingLists/En
So our beloved admin(s) could just create a "devs" list, with writing access disabled before a member is allowed by an admin, archives available to public (I don't think discussions should be hidden), et voila !
I am not sure how the spam control is working at tuxfamily. If good, inscription (writing) could be public.
Please remember an issue I have noticed with other mailing-lists: We will need a few users from gmail, gmx, yahoo, etc... to verify that emails coming from the list are not in SPAM (SPF/DKIM signatures could be a problem depending their handling by tuxfamily). Torvalds did complain a lot with Google (he uses gmail) when he noticed all kernel emails were in spam after a change on gmail server side (corrected since then, at least for him).
What do you think ?
