In other words I can go in and correct those mistakes you quote.
Then you would get banned for vandalising the article because your opinion of what "title" should mean is not the only truth.
Because as has been stated Captain is not a title neither is Admiral, Ensign or Ambassador they are ranks.
This is more than an oversimplification, but in fact it is flat out untrue - they are both.
If you are a Lieutenant in command of a starship, you are called Captain by the crew, not Lieutenant. This makes "Captain" a title, regardless of the fact that it is also a rank. That is beyond the point, though.
The point is, that that field is called "Title" simply because it's shorter and easier than "That word or phrase you want to appear over your head."
Ranks, real "Titles," and plenty of goofy things can potentially show up there. Is "Crash Test Tribble" really an apt rank or title?
So what you're REALLY asking for, if I can understand it properly, is for us to add in titles based on accomplishments, yes? You want to be rewarded for completing the crystalline entity fleet action with the new title of "Survivor of the Crystalline Atrocity" and the like.
