UPDATE:
We discussed this in our call yesterday and decided to create a basic document for the global OSCEdays which outlines the positive, inclusive aspirations of our community, and sets some basic guidelines.
This week I will copy+paste some bits and pieces from existing codes of conduct to create a draft which we can then discuss and improve.
Alongside that document, I think it would be useful to link to resources about Codes of Conduct and include an invitation for local events to consider introducing a code of conduct, making people responsible for dealing with issues when they arise etc.
This is not something that local teams MUST do, but it would be good to have the information there for them so that if they decide it is a priority, we can make it as easy as possible to implement.
