Many members now do not bother leaving comments to explain their SH ratings, including me sometimes. Please note that we all have a limited time frame to rate, read and write so be thankful that someone took the time to read and rate yours . Read other reviews under the same category as yours to figure out why your review is rated lower. And be courteous those members who rated you and rate them back, regardless of the rating they gave you. And, don't expect too much.
Patience is a virtue to live by.
It took me months of hard work before I got the hits and the trust. Don't give up. And, as always, thanks for reading and rating my reviews. I try to keep track of those in my WOT and those who have rated me. If you need to contact me via email, in the email subject area, please indicate something about Epinions or I will not read it since I use hotmail for all my spam mail and block everything that isn't in my contact list.
