Hi,
Currently we have apart of the git list itself two places where we have added contributors in past, but which look quiet orphaned nowadays:
The contributors-dialog on Geany->Help:
https://github.com/geany/geany/blob/master/src/about.c
and the THANKS-file inside / of the source tree:
https://github.com/geany/geany/blob/master/THANKS
As we got a huge amount of contributors¹ all should get their kudos and now I'm wondering how we can go on in future with it. There are contributors for translations, code, documentation, community things like support, donations (money) etc.
Cheers, Frank
¹ Openhub https://www.openhub.net/p/geany says we have 42 (hihi) contributors last year -- not counting po updates where I committed the po files myself.
