This plugin seems to be adding some additional tag&prefix settings for blogs, which I'm trying to use.
I want to override the "Minimum Tags Allowed" of a group blog in its "Blog Settings" (AdminCP). I removed the check from the "Default" option, and put the value "1", for example, in the input field. However, after saving and going again to the settings page, the value I set disappeared, and the "Default" option is checked again.
So, it seems there is a bug preventing the changes made from being persisted.
