Yes1. I feel that it would help out, but only if someone can make a really good system, and is able to find something that can punch out numbers to the stats, seeing as if a person were to do it, they could be biased.
Yes2. Though, I think anyone should be able to make new jutsus and clans, and have a trusted MOD look over and say yes or no to jutsus and clans.
No3. We want people wh are serious about rping, not people who will post one-liners. Luckily, we already have a system that disallows the less intelligent RPers from ruining things. :-D
No4. Because sometimes, things happen, and you can't get online in time to say you won't be online. For example, someone you know dies and the funeral is very soon. It is also out of town, and you don't have internet access there, and you need time to greive.
