What it says on the tin - I can only see the total number of games I voted for and the number of wishes which have been fulfilled, but is it possible to somehow view the exact titles that I voted for / were fulfilled?

Aside from Ice_Mage's "solution", nope. Can't even find one's own game reviews here. Or edit them. Meaning that say, some event transpires or an update ruins/fixes a game, there's no real recourse.

I haven't checked out the url solution posted, but you can also do the following.

Make a list of the games you would like to vote for, then visit the Community Wishlist for each.
If you have voted for the game already, being able to vote again for it will be grayed out (unavailable).

Not perfect I know, but shouldn't be necessary very often, especially if you keep a list handy to cater for memory issues.
