This is actually what Agoracom quotes when you click on your profile...

"How do i go about doing so? Can i give a poster a thumbs down to balance it out as well? Some might think it's a hail Mary posting but this is what makes these threads fair, not everyone sees it that way and some of these thumbs up postings are tiny green lies imvho..."

Thanks for your response but you haven't fully answered my queries, why are u making me repeat myself? Please answer my questions.

Thanks

ps...it's good you can only recommend a post once as this system would not work, not in the least.
