Reever: Haha, I actually wanted to write a "In case you wondered why I'm asking..." but I left it out then :D
No, I was just thinking for cases like the Secret Santa, where you wouldn't necessarily want *some* people to see all your wishlisted games...because they might go broke or something then :D
So as long as I'm not in full control of what I can show or not (at least not easily), I think I'll stay away from the wiki =)
There is another option. Your user page on the wiki is just a regular wiki page which you can edit to display whatever you like. Adding the custom element <gog-wishlist user="Reever" /> would cause the wiki to automatically display whatever your wishlist on GOG contained, but there's absolutely nothing forcing you to use that element - you can leave out the wishlist entirely or simply write your own list instead, containing absolutely anything you want.
