Is there any way to see all my "community wishes"? I ask because I don't quite remember what games I submitted to the "community wishlist" and I would like to see if they were accepted by the rest of the GOG community?
I know it's a bit selfish of me, but I'd like to have a "so-so" insight into what I was adding to the list.

If you either created a wishlist entry or commented on it, you can try entering "your username here" inurl:wishlist site:gog.com into a search engine. If you only voted on it, then you're out of luck.

Try to use quotes "" as Ice_Mage has suggested.

Like this: "Tominion" inurl:wishlist site:gog.com

I tried to do so and the google search engine has return only 1 search result though:

https://www.gog.com/wishlist/games/haunted_chocolatier

If I try that, I get shown one(!) wishlist entry that I voted for.
Now, I know for sure, that I voted for a few more, and I even may have created a few WL entries myself, so...
