We welcome any extra hands offered; thanks for taking the first step in reaching out.
Do you have any particular projects/goals/ambitions for C2C, then that is fine, and we would like to hear about it.
If you to begin with just wanna be backup and do small tweaks, and misc stuff here and there, then that's cool too.
We may try to delegate work once in a while, but it is entirely voluntary to accept such delegation. Will usually just be an annunciation like: "this or that needs doing, anyone up for it?"
There is no individual result pressure on this team, we only expect good teamwork, which means showing considerations for other modders work, and that we don't step on each other toes.
Clear and honest communication about what one is doing, or intend on doing, helps a lot in regards to being a good team-member. Being able to discuss and compromise when other modders object to your intent/work is also important.
Introducing bugs one is unaware of on the master repository is something everyone does once in a while; and as long as you are dedicated in clearing it up afterwards then no harm done is how I see it at least.
Us moving over from SVN to git now in the imminent future will make it easier to work with branches which will add another layer of quality control for stuff pushed to the master branch.
Welcome to the team.
