My blue star becomes RED? what happen?

I wonder what it means. I havn't even paid attention to what color the stars were or other such things. I would say maybe email mylot and see what they say.

You're still a "high 9" meaning you're close to a 10. You're right on the edge wher it doesn't take many ratings for your star to change in either direction. You probably didn't make a major blunder. You might have just gotten a few -'s (not everybody understands the right way to rate so you may not have offended anybody at all, some will give -'s for stupid reasons). Also a star can drop even if you give perfectly good responses to discussions that wind up deleted. Your post gets deleted with it and that's never a good thing even if it wasn't your fault. My star went back and forth a bit when I first started to...had a 9, then a 10, then a 9 again....My 10 has been stable for a while although I did drop as low as a 95/100 and as high as a 98/100.

ive red a post asking infos about star number and color, one of the respondent there said that the color means nothing what count as an increase in reputation is the number, that is what that person said, me i dont really know what the colors meant, i think if you have offended someone your number will drop, i dunno

First, can I ask what the stars mean? I am new here and am not sure what everything means yet.
