User:WonderBuono!/List of members by time in H!P

I have an obsession with making lists for some reason. This one is basically just for fun.

I'm not too concerned about the details, so I just did the times by the largest factor (years in most cases, but if the person has been a member for less than a year I'll do months, and in the rare case of less than a month, days). And I'm basically just counting from the first to the last year; so like, if someone was a member from, say, December 2010 to January 2013, it would be 3 years, not 2... even though it's basically two years and a month. Because I'm lazy and don't feel like counting exact times, okay?

If you're wondering about the 1st gen and Heike's timelines, I'm considering their join date to be the creation of H!P in '98.
