Anyone want any info, I have a word doc thats give you all the pointers you need using a proggie called PowerGrab (freeware).
Powergrab has been updated since but the principal is the same and configuration isnt much different.
Go
here for it if you want a peep.
Its hosted on my own webspace so its not leeched or pirated and it is safe.
