Description
What's the problem this feature will solve?
Sometimes the moderators have to make decisions about projects, such as applying different upload limits to them (e.g., #6116). Sometimes those decisions then get changed based on new information (e.g., #6394). But there's no ability to link a github issue or slack discussion to the project, so determining why the settings for the project are in the state that they are requires some spelunking through github issues to discover the history.
Describe the solution you'd like
Perhaps it would be nice to have a place for moderators to record information about the project and its changes on the actual project?
Alternately, it could be something more akin to the journal entries, where moderator actions are allowed/required to provide a string for the 'action' field, and we could put a link to a github issue there.
