come up with a good message to set context for contributions

[travi]

• make it very clear that we have very little bandwidth and no budget for maintenance and that one of our primary goals is to keep effort to a minimum so that we don't drop important responsibilities
• our first priority is making sure we have meetings organized each month
• maintaining other stuff is secondary to that primary goal
• maintenance effort will usually be given to tasks that reduce the effort of the first goal over other tasks
• we welcome help from the community, but are careful to protect ourselves from contributions that will complicate maintenance efforts once the contributor has moved on
• it is a good idea to give us a heads up about a contribution early so we can make sure we're on the same page and would accept the contribution. having a conversation with the maintainers by opening an issue before putting effort into a PR, etc is a great way to help the process go smoothly
