Reduced ratings...

I think you should refer to the Mylot guidelines on posting :) They had brought out an alert last week about reduced ratings in case there was a discussion that you had probably started or had responded to probably which was flagged and hence deleted.. Since that post had contributed to your rating, once deleted, your ratings was also reduced. I am not so sure about ratings being reduced for a "-" rating by others..

the reduction in rating may b becoz somebody may have rated ur reply as -(negative)
