Requested feature overview description.
Allow users to search the tag history of all posts uploaded by a specific user.

Why would it be useful?
Enables a user to monitor tag changes of the posts uploaded by a specific user. The 'username' search option only shows changes that a specific user has made, omitting changes to the same post made by other users.

I would like to know if there are any specific tags that I miss when uploading images. I have noticed that some of my uploads have tags added by other users, but the only way for me to know for sure is to check each individual post's tag history. I have over 1000 uploads, so this would be a hassle for uploaders such as myself.

Being able to view all the tag changes to my uploads will allow me to notice any patterns, especially seeing tags that I frequently miss. Ultimately, this will allow me to improve my tagging behaviour, as well as anybody else who uses it in a similar manner.

What part(s) of the site page(s) are affected?
Post tag history

You don't need to check every image you've ever uploaded for tag changes, only the ones you've uploaded within the last day or two. Other users will pounce on the image to fix tags within minutes of uploading if not seconds

Within a few minutes I've already found at least 7 different images that have had tags changed by users other than myself, more than two weeks after I uploaded them. The majority of tag fixes seem to occur within a few days, but I'm interested to know what mistakes I have made and what tags I have missed. It is very difficult to notice recurring mistakes by looking at the tag history of individual posts, rather than together in a list.

Right, because it's a community tag effort. You don't have to be perfect when you upload or spend hours getting the tags right

Asking your tagging to be analyzed on the forum is always an option. If you don't mind having your mistakes pointed out in the public, that is.

Lemme just take a quick glance... Nah, no major problems as far as I can see. And I don't remember seeing your name often when I'm hunting for mistags. Overall, your tagging is clearly above average.

As for the feature request? Yeah, I could see that being useful.
I've occasionally browsed the tag history of my older uploads, and found some questionable changes that went unnoticed for ages. Having some way to spot those faster would be nice.

I disagree. I've looked back at some of my older uploads and found users vandalizing the tags based on things like Pokemon Dimorphism, which we don't use. Being able to look at a tag history of my uploads would help me track down these recent changes to older pictures and figure out if they're good or bad.
