If you're not going to change every instance of tauredain to taurethrim (excluding image links) on a page, I'd rather you not do it at all. It just makes it more difficult for the person who has to fix it.
Here is the edit that I did after yours in which I changed over 30 instances of tauredain to taurethrim.
If you want to help, here is what I told another user on the matter.
Go through a page in source mode and use your browser's search function (ctrl + f) to find all instances of tauredain/moredain. (I just search edain because it gets them both) Change all of them to taurethrim/morwaith except for file links. Don't forget to check and change the category as well.
If you find a link that looks like
Please change it to
Don't worry about red links for the moment, we'll come back to those at a later date with this tool.
Lol sorry i probably don't even see you on the second age but I am giltri lord of the ironfists (which is one of the four red dwarven clans). I just like being friendly and adding my name to peoples friend lists (sorry for the inconvenience.
Zurgor is custom character. After the rings of power were given to dwarf lords of Orocarni. Dragons from far away came and atacked the dwarves of all four clans. All dwarf kings of all clans except king of Stonefoots were killed and their rings consumed by dragons. Last of 4 dwarven rings was hidden and dwarves exiled from their mountains. But later Zurgor son of king of Stonefoots who hid the ring united four clans of dwarves who were exiled. And together with Avari elves to whom he promised riches as reward and some easterling tribes who he promised riches too marched to all 4 dwarven cities and with ring of stonefoots who he found after his fathers instructions killed all dragons but with costly victory. Almost all dwarves elves and easterlings were killed but thos who survived got their treasure and because dwarves were so few they all moved to city of Stiffbeards called Negrod where Zurgor ruled as king of Orocarni. But after his death dwarfes fought for leadership of dwarves and dwarves split again into four clans. And later dragon Grudor atacked stonefoots and destoyed the last of Orocarni rings. I have been count of Dol Guldur on harda and will be Ulfang leader of easterlings on First age server. I would like to be leader of Orocarni dwarves cause I havent been dwarf and I would like to be orocarni dwarf cause Tolkien wrote really few things about them which makes them easy for custom lore.
