Well, semi-literate level is pretty vague on CS. Some SL rps require 3+ sentences, some a paragraph, etc.
Personally, I'd classify Semi-Literate as two small, or one big paragraph, meaning, about six sentences, at least.
Because, the way I see it, just because something isn't a one-liner, it doesn't mean it isn't Illiterate.
On that note, Semi-literate is a pretty common term ^^ In rping and writing, Illiterate, semi-literate and literate basically replace novice-beginner/intermediate/advanced.

Guys, I have an idea for a rp. It's a teens with powers, plot being about a man dying of cancer wanting to take over/destroy the world. And the teens have to save it. I came up with that today, so I haven't got other things figured out really. If anyone has any suggestions, please speak up ^^
