dear Lester Chan, accept my thanks for your rating plugin, that's amazing!
you're developing it from 2006 until now,
and i think time has come to push this module to the next level of usability!
many of us (web designers) need to use of wp-postratings twice on a page for receiving more rates. one in the header of single post pages, and another in the footer of single post pages.
please plan to correct this problem, we would be happy and thankful for that :)
