Any chance in heck of ever getting a tagging feature, like Facebook has? e.g. When someone writes "Paging so-and-so", if they would start the name with a @ (like this: @so...) and a small list would pop up of suggested names of members that match what has been typed already (like when adding a recipient to a PM). The name would then be hyperlinked in the post to the member's profile, and the person being mentioned would be somehow notified that he was mentioned in a post.
This would be especially useful for catching someone's attention in a thread they don't follow. For example, on more than one occasion, someone has written "paging Moishebatchy" and I didn't see it until weeks later, or written something about me (and mentioned my name in the sentence), but I never got to comment on it because I never even knew it was there.
