Forewarning: I know absolutely nothing about the canon. You'll need a second beta for that. But I will help you out with grammar, spelling where you're speaking English (and possibly Spanish!), and syntax in general.

Example:

I need somebody to help with my Agent's character sheet and intro. Help, and I will reward you by writing missions.

Just let me know what exactly you're looking for. Do you want me to go over it with a basic red pen and fix extra/missing commas, add capitals where necessary, etc? Or would you like me to actually dive in and edit the thing? Because I can do both, but it's good to know what you're looking for, first.

I'm sorry that I can't help you with this, but I am no good at grammar and punctuation issues. My own commas need to be herded to safety before I can post stories. I hope you find someone soon.
