I want to know how many votes I made on questions and answer's still. Is there any way to know that ?
In your profile page, you can find a summary of your votes at the bottom.
But to see the detailed history of your votes, click on the
votes tab in the your profile.
In your case, the page for your profile is at http://meta.askubuntu.com/users/263205/a-j?tab=votes. (Votes are private, so this page is private for your eyes only. Not even mods can see it.)
