Thanks T6.
I already have all the individual "Home" sections allocated to a separate /home partition, each listed as a sub folder eg LXDE/home, PCLos/home, and would prefer to keep them as such to avoid any crossover (sorry, i should have mentioned this above), but this method also leads to problems with permisions, especially when adding "testor" users.
I would like to keep two separate distro's in use as i tend to use the machine for testing (not having a separate machine for this purpose) and too often break things.
As a result i often have to reinstall as my recovery skills are very poor, and the bookmarks/passwords are a real pain to keep restoring.
