Rules consist of the standard no godmodding (over powering your character and metagaming-your character knowing things they shouldn't and have no way of knowing) and no killing off another person's character or controlling them with out the player's permission.
I believe the rating is probably on a PG-14 scale if that's what you mean.
I can't remember who did what in HH3, Starry. I think we both pulled off a time skip. I know I did in HH2. Just PM me what you need or how to help.
As for events, Scared, nothing really happened save for the new Titans basically getting to know each other. Athena and Matt were already friends and Athena restarted the Titans and Matt reactivated the Titan's Tower.
Snow and Nova later joined, followed by Red X. Olli helped them out with a super powered bank robber and his leg got injured and now Matt and Red X are almost friends with him.
Someone broke into the Tower while almost everyone was away and now we're getting ready for a time skip because we all left or got so preoccupied that this RP died.
So, its pretty safe for you to jump in after the time skip. I'm thinking that things are gonna change.
That's DEFINITELY I want to do. However, I think it would be best for that to happen via PM with anyone who takes parts. Then again, there's no telling what anyone has in mind until its done. Plus, this is an Unhosted story. Something like that usually goes down in the Hosted section. But I don't see why we can't do that.
