Welcome to developer area. We are currently in process of setting this new drones-discuss area here on our new discuss server.
If you had account already on old ardupilot.com/forums you can use that in here too. Just let us admins to know your old drones-discuss email address and your account in here and we will upgrade it shortly.
As we try to keep this area highly focused on development issues, you need to be in Developer group to be able to post new topics.
Developer area rules:
New users - readonly
Normal users - read/reply
Developers - create/read/reply
To get added: Contact moderators/admins
Happy developing to all
