So in the short time since my last post I have exported my LibraryThing database, created a Gurulib account, made a screen dump and saved it as a jpeg file and am currently importing my LibraryThing books into Gurulib. Easy!
Initially I didn't think it was going to work - look at the page I got. Check out how long until it thinks it'll have downloaded the stuff (6 days, 23 hours, 56 minutes, 57 seconds)!!!
