Going to get right to the point....

1. I usually post once a day. No, I don't expect you too. I understand we all have other lives and we get busy. I would say try and post within 2 or 3 days. Unless you tell me otherwise. 
2 I write in 3rd person, I expect you too as well. 
3. Length that I am looking for is 1 paragraph or more. Quality over quantity. 
4. I normally do mature themes (think of an R rated movie). With that in mind I only do PMs or over email to make things easier. 

Here are some genres that I love doing and are looking for. 

Post-Apoc
Future/sci-fi
Harry Potter
Star Wars
Star Trek
Modern/Fantasy
Medieval/Fantasy

If you have other pairings or genres please suggest them. If you are interested in talking something through, PM me. I look forward to hearing from you. :)
