SPAM THREAD ABOUT OUR LEVELS ON MPGH

i appologize for this post, i know i shouldn't post this here, and should probably go to the help thread, but i dont need any help.

i was just wanting a quick explanation about the bars beneath our user names.. the red and green bars.. i know the green bar is our activity.. but i dont understand the red bar.. i have over 3,000 points and i am level 1, yet "alexrules" has 685 points at level 13.. could anybody answer this for me?

edit: and why has my activity gone down to 0?? it was at 17% last i saw, now its showin 0%

ya thats weird cause im like a level 16
