Where does this go and how does it affect leveling? Is this the reason why my first toon didn't go get it's mount automatically at level 20 because I never copied the GoTo folder?
you don't copy anything... you svn the whole svn and that's it and no, the goto folder doesn't get the mount if it's horde, i fixed the issue of you not getting your mount a few days ago (make sure you re-svn daily)
Is it best to SVN to my HB folder and load from there? I've been making a Profiles folder in my HB folder, copying what I need, and going with that. Horde is the faction I'm playing right now. I also copy plugins and quest behaviors as instructed. Yeah, always re-SVN. I'm hoping Mr.ItemRemover plugin speeds up leveling with less cluttered bags and trips to vendor.
Is this only if you started without using the profile at all or manually starting doing something that receives experience and gained a few levels such as dungeoning?
