The only way for you to know what 'rank' you have is when you make it into the alltime user ranking top 100 right now... =/
The other rankings are in between rank # 100 and # 10,000 at normal activity probably. But this is also probably changing all the time as a lot of users have the same or close AP counts at any given point in time!
Probably yes... but not in the same way as it is right now. The new ranking system will be different from the current one, but what ranks there will be is unknown. What IS known on the other hand is that the points system will be separated into AP (ArmorPoints) for game rating/reviewing and highscores and KP (KarmaPoints) for activity and community, but the latter is not a fixed name yet. =)

where can i find the rankings between 100 and 10,000 because last i checked when it was up i was in the top 2000 and i've got probably over 500 AP since then
