This is all fascinating to me because I would not think linking to the files would give you any change in performance while loading because the exact same files are being hammered unless by linking it's causing it to be cached in memory differently?

Also, the WTF are separated by accounts and I just browsed my WTF and I see no config files outside of each account folder so since you can only run 1 toon per account I would think that there should be no conflicts having all WTF in one place and bongos2, possessions should all work properly. Once I get a new system put together I'm going to link all account folders into one location but have the main Config.wtf separate since it contains resolution info and I'll have different sized windows running.
