I read your post, and I think I may be able to help you out (assuming you are still looking for a kinship).
Who are we? We are The Northern Kingdom, located on Imladris. Here is a link to our recruitment thread. You will find a good bit of information located here.
Our members come from all over the world, however the majority of us live within the United States, so hopefully we won't have too much trouble as far as activity goes :P
As for kin activities, we group up frequently, but we also allow our members plenty of time to enjoy the game for themselves. We also tend to focus on all content, not just end-game content (although we do wiggle our way in there).
We also try to keep a sense of equality in the kinship. All members are equal, and are treated as such (that includes officers and the kin leader), and they all have the same or similar expectations. Officers and leaders do not command members, rather they are there to guide and moderate. We prefer a style of leadership where members are capable of managing themselves without an officer breathing down their neck, however the administration will step in to preserve balance if things get out of hand. Over all, you'll find a very friendly, helpful, kind, and easygoing community that aims to give its members the best out of LotRO.
Interested? If so, feel free to send me a Private Message on these forums, and we can get in touch.
