I can tell you
There is a huge different for leveling up once you reach level 10. Of course, sine you contributed a lot last weeks, you didn't notice it. However, now you should realize that leveling up is a bit harder. I usually get about 1.0 % for every trivia, episode cast/crew submitted and something like 1.4 % for every summary/episode submitted. Also, the level system has been buggy the last days. Hope that helps. Have a nice day!

Ugg. I can't tell you, sorry! I think Estaban pretty much covered it. But I know what you mean. Every time I go up 1%. By the time I get on the next level, it will be next year.

Thanks guys! I guess I'll be submitting a lot more now.
