There are times when someone in an admin/mod group will warn a member only to have the rest of the group determine that the warning isn't justified. But there doesn't seem to be a way to correct the error. the warning is in effect until the boards predetermined length lets it go.
At the moment you can delete the User note about the warning. MCP > User notes > username > User details > mark > Delete marked
What I would like to see is a way to remove/delete a warning before the predetermined board setting.
Anyone interested / willing to create an extension for this?
