Long story short (which for me will mean probably 4-5 pages

):
I just joined a dojo after a layoff from Aikido and a move to another city. I've tried out other dojos and the temperament, etc, never seemed to fit what I was looking for. This new dojo feels like home.
However, the instructor (who really knows his stuff and I'm happy to be working with him) has left an organization and struck out on his own. So he has no current affiliation with a larger organization.
So questions arise:
1) He doesn't place much emphasis on ukemi at all. While this doesn't affect me per say since I have been taught rolls, breakfalls, and my ukemi isn't TOO bad, I'm concerned for some of the newbies there who aren't learning to take ukemi well, nor are they learning to protect Uke when they are performing techniques. Any thoughts on how to approach this subject once I become more integrated into the group? What about convincing him to let me teach a "basics" class? It's a small club that's growing exponentially, and the Sensei is young and my suspicion is he honestly just hasn't thought much about it.
2) Our sensei is not affiliated with any organization. So how will any rank he gives me be looked at if I move to another organization? As a former member of ASU, I was comforted to know that when I tested under my sensei and awarded a rank, ASU kept a record of it. While the training and my growth in Aiki is most important to me, rank still has some important to me. Is it possible to perhaps GET us affiliated with someone if the sensei likes the idea, and how would I go about that?
Or does my perspective just need changing?
Thanks for the help.
