I can't find it and I want some add-ons...can somone help me? thanks

before you try to use addons i suggest you learn by yourself how to find the directory

If you want to install an addon, put the folder of the addon (unzipped and such) in the Warhammer Online addons directory. ( C:\Program Files\Electronic Arts\Warhammer Online\Interface\Addons ).  However, that location varies from computer to computer. If you want a real explanation, go to an addon you want to download and scroll down halfway and look at the Installation tab. If you want extra help, just Private Message me, I'd be happy to help you.
