You do know that integration is usually a choice, right?
Personally, I'm for staying multiple. That doesn't mean I'm not for healing, or for processing everything, or anything like that. I am. But it can be done without integration. Each individual part can use therapy and stuff to help them with their own wounds and troubles, and that overall will help the system as a whole. You can work on increasing communication, memory-sharing between each other, co-consciousness, co-hosting, and switching at-will. You can each heal at your own pace; share memories with each other so no one has blank spots; you can all process your memories at your own pace before processing them together; and you can become a fully functional, healed, smooth-running system/team. That's our personal goal. We like our "family of one", and we don't think we need to integrate to become just as functional (if not better

) than any "normal" person. Sure, it's a process, but so is integration. And the few days where we've had amazing system functioning and team effort, everyone helping each other, each other's strengths helping with each other's weaknesses, it's clear to us that it's a worthwhile process. When we're functioning as a system and a team, to our best capacity, it's awesome. And once everyone's healed, memory's are fully processed, and everything like that, we'll always be able to function that well. And that, to us, would be perfectly fine.
But this thread might be helpful to you, it's about integration. It might be a bit difficult to understand at first, but don't be afraid to ask questions, I know the poster is happy to answer any questions and help make her posts more clear/understandable to people.

Here it is:
http://www.psychforums.com/dissociative-identity/topic100124.htmlI'm not much help as far as integration goes, but the poster of that thread knows TONS about it, so they'd be an excellent person to ask about integration.
Other than that, the only thing I can think of is to search for integration threads on here.
I hope I was somewhat helpful. Good luck with this!
