No worries Ed. I've just written the mbox repository so I've a good idea what works etc. in James
My only comment is the use of the .select() method. When a user's repository is opened the method call is .select("username") To access folders I'd propose the use of .select("username.foldername") when the server want a folders contents. Folder links are interesting ;) I'll have a think about those too. Shared folders are a LOT of pain due to the fact that you'd have a store the read state for lots of people at the same time. Not nice.
