that's just it, there IS no visible vote button, nor anything that pops up on mouseover. i TRIED to vote. wierd? i have to use ie6 because ff does not see the editor that this site uses. i was having the same issue on artzone but they fixed it so the rich edit was OPTIONAL and i turned mine off so renderosity is the ONLY site i have to use ie6 on (thankfully, since i hate ie any number).
in anycase... usually if there is no vote or sumbit button there will be a little hand that pops up where it is located. just not on this contest thing...
