The problem with "Free" is that one-liners are extremely abundant and annoying. If those one liners meant anything, then it would be okay. However, couple the one-liners along with the people who lack any grammar whatsoever and whose posts are really shit-tier. There you have the average "Free" user.

Then you have the Casuals, which mostly fall in the category "High Casual to Advanced". People here write 2-5 paragraphs of really good consistency, following gramatical rules with little typos, etc. This place is really appealing because the section is for Casuals, but the content ends up being for Advanced.

Finally, we have Advanced. Half of the GMs have ridiculous standards for this section (I remember one particular GM who had the requirement of no less than 2,000 words per post, which I found idiotic to the extreme.) The other half end up lowering their standards to Casual, but since most RPers are scared of Advanced due to thinking that it is a lair of "Only-pros", Advanced ends being abandoned.
