You can merge them together yourself, and if you need help you can ask on the discussion page. You don't need permission to delete someone else's content as long as the deletion is clearly explained.
That was the amazing part. Things just keep going.

When someone adds content to a public wiki, it is no longer "their" content. So go ahead, edit the hell out of their stuff. Merge those duplicates! Fix that factual error! Delete that shoehorned non-example! You have the power!
I didn't write any of that.
"In distress", my ass.
More seriously, there are a lot of editors who seem to be afraid to edit existing entries, instead adding a sub-point that breaks Example Indentation, often with a bout of Natter to boot.
Please don't be one of those editors, Wraith.

No, the other one.

I'll also note that getting to the other extreme is also not advisable. So don't delete whole entries just because one word is Word Cruft or something similar that can be fixed with a minor effort.

Quick question: If I see two entries about the same work on the same page can I just merge them together as best I'm able or do I need to ask permission somewhere since I am technically deleting someones content?
Side note: It seams to happen most regularly under the video games sections which does not give me a lot of hope for my fellow games :/
So many tropes so little time...
