We couldn't care less about how old someone is, how many posts they have, how long they've been on the guild or anything like that. The only thing we care about when we host an RP is whether they can produce something of a quality we deem fitting for our RP. Sure. That could mean that some people might not get in, but that's too bad for them.

We'd much rather take the thirteen-year old who looks able to write good, clean english than the twenty-odd year guy (or gal) who can't spell correctly, let alone get grammar right. In fact, had you not provided a number for your own age, we would naturally have assumed that you were considerably older. 

As for the bit about free? In our experience, free tends to have terrible grammar and spelling. There might be RPs in that section where that isn't the case, but we've not seen them. Mostly because its not a section we venture into. Despite what many seem to think, if you're able to write five paragraphs, you're well within the parameters for advanced. 

Our current RP is in advanced, and the only difficult someone young might have in there is the fact that it'll deal with numerous pretty dark themes. What we care about from the posters in our RPs is what they achieve with their posts and how much thought they put into it. Not whether it has [i]n[/i] words or paragraphs or whatever. Making a high-quality character sheet is key.

In fact, if you think you can handle dark themes (will likely include torture of both emotional and physical natures, death, betrayal, etc...) and you're into Star Wars, then feel free to check out our RP, [url=http://www.roleplayerguild.com/topics/153777-calling-all-jedi-and-sith]Coruscant Sacked: Aftermath[/url]. Its not for the feint of heart, but we judge people only on what they produce, not on parameters like the ones described in the first sentence of this post.
