I've posted a screenshot of how to remove votes from your previously voted on items:
Also the votes DO reset once an issue is closed. I'm not sure where you're getting your info (or maybe the site has been updated since you last looked into it.) Lastly, I've seen Fizzer close a repeat issue and redirect somebody to an existing issue with the same topic. Who's fault is it for reposting an issue exactly? It's the fault of the person posting who didn't search for the issue prior to posting. Either way, can you think of a better way to post your ideas? I certainly can't. Putting them on the General forum is hardly a better way.
