When you can look at the thread title, look at the last person who posted, and know exactly what that person's post will entail. When you know which "buzz words" draw certain posters. When you know more about LGMers than there own family members. *Guilty*When you don't post for one day and all of the sudden the MIA-Squad is hunting you down. When you can tell who don't like who just by the way they post. When you've made "voices" for each LGMer and you read their posts in those "voices".
When you can tell who don't like who just by the way they post.
When you use LGM smiley codes on other sites like FB...
When you know by the screenname that there's a guitarist posting in the bass forum, or a bassist posting in the drum forum, etc...
When you know just about everybody's gubment name, well at least those who post the most.
