1) The WIKI, still a work in progress, has been updated. It is a rough overview, a starting point for people who want to learn about the issue. It is also very UK-centric at the moment so any significant cases/people from elsewhere will be added as and when.
The link in the sidebar is broken, direct link here
2) From the start of this circle we have asked people to format the title of their posts with a date as this is a catalog/archiving circle
This is spelt out in the sidebar and welcome post:
It is a nuisance for both mods and contributers if we have to delete and ask for repost - especially if a discussion has started.
Given that too many people are failing to read these rules, users and mods can now add the date as a flair if necessary (after the 5 minute title editing window is closed).
