A question about changing copyright tags

There is a tag called "happy margaret" that someone posted, with a bunch of cg images from the game, and they looked familiar so I looked into my collection. I have the whole cg collection, but it's labeled "Happy Mararette!"

So how would one go about changing the copyright tag, so each image would display the correct tag instead of the old one?

In this case, nothing, since happy margaret is the correct romanization of はっぴぃ☆マーガレット！ (happii maagaretto). I don't think the exclamation mark at the end is of vital importance, or if it can be used at all, in fact.

In other cases, I would either 1) change it myself if it's a really small copyright (around 10 or less images) by simply replacing the old tag with the new one or 2) ask the forum for opinions. 2 is preferred, especially if you can't read Japanese and your sources are dubious.

Exclamation points work (see post #165883) but I believe they aren't especially wanted in tags (see the discussion at post #155429, although it seems that oh!_great stuck around anyway).

Mmm ok. Just wasn't sure which name was correct, cause I had the whole collection, which is like... over 700 images, but I guess if it's right, I'll leave it.
