Oops! Your question couldn't be submitted because: • 'faq rules stackoverflow discussion ' contains a tag reserved for moderator use
User should be told which specific tag is needed to be removed to comply or, perhaps, the system should automatically remove the tag automatically. I should not have to use trial and error to solve the issue.
As a side note, the offending tag was FAQ which seems rather odd since this would be the site SO would send people to talk about the FAQ.
