Peple have been pretty good about this, but I'll still ask people to refrain from posting large images. Please read the guidelines HERE before posting large images. ~ Dakia
Due to the popularity of the thread I made showcasing my WoW Style Interface for TOR I thought I should make a new thread for the sole purpose of showcase custom player UI's!
Here's the original UI I uploaded.
UPDATE 19/04/2012: I have now uploaded a new WoW Classic Style UI (Download has been updated). Take a look at the new screenshot, I've tried to match the actual WoW Interface much more closely and I actually prefer this one and use it myself. The original one I made is still in the download if you prefer it.
Download: http://www.swtorui.com/downloads/info89-WoWUI.html
To install just place the .xml file into the 'C:\Users\<USERNAME>\AppData\Local\SWTOR\swtor\settings\GUIProfiles' folder and select the profile via the in-game Interface Editor.
So, everyone please feel free to contribute and upload your custom UI's! Please provide a screenshot and a download link if you feel like sharing
