The “introduceyourself” tag is for creating one introductory post that tells us about you. Users are encouraged to use this tag exclusively for that. A lot of people use it because it's a popular tag, but it will just annoy the more serious users if things are uncategorized - might get you flagged. Please use only relevant tags when posting.
Blatant misuse of tags is spam. #Spam is discouraged by the community.
