We're working on adding 5 more levels to the site. We'd like most of the members of the site to experience the new levels, so we'll be easing up some of the requirements in the 31-40 range when we launch the new levels. We'll also be creating a Hall Of Fame page for the few members that were able to make it up to level 40 before we launch the new levels.
With the new levels you can expect some point/fubuck requirements like in the past, as well as the Achievement system and other requirements needed to move up from 41-45. We'll also be nerfing some of the older requirements that were bottlenecking too many people (such as the spotlight requirement :)).
ETA for levels 41-45 is about 1-2 weeks.
Stay tuned... we'll have a few surprises in there too and some new abilities for you to unlock as you level up. :D
