There is a problem with the Sub for GTA Online. In order to post stories or things they did in the game they have to post in a single thread. That means a single thread will have multiple stories, posts, quotes, and replies. That means you my have to go through pages of stuff you don't care about or want to read, etc.
It is unorganized, unprofessional, messy, and almost useless. People should be allowed to post stories in general posts or perhaps have a sub of it's own, but having a sub of it's own seems not needed. Perhaps that is why the thread is like this in the first place.
The logical thing to do would be let people post general things and stories in the "Online general sub" or it's own sub under Online. Just my suggestion. It works on almost every single forum I have ever seen or been on.
