Another suggestion regarding the LinkedIn process:
Since Groups and Associations can be publicly available, I would rather not post my YC-handle there. Rather, when a user makes a request to join, LinkedIn allows them to send a msg to the group manager. It would be better if we can use that to let you know of our YC-handle so you can figure out the real requests from the SPAM requests.
I didn't have that option when joining a group recently, feel free to send me a message as an alternative (or even email, if you feel so moved). I just want some means of filtering for folks that are actually participating in the news.YC community.
