Hi Stephan, Thanks for your reply! I'm currently having a look at the API reference. As a first stage, I will implement the FileSystem using userlandFS and not FUSE as the ultimate goal is to make a real kernel add-on. "The UserlandFS server is missing some features which would allow it to integrate better. Features like auto-mounting or partitioning are not easily available as a result. If the IMAP FS implementation shall stay in userland, the UserlandFS may need to be extended, although the missing features may not affect the IMAP FS so much, I don't know." I'll have a look at this. On a related note - can you tell me who would be willing to mentor this project (Would you be willing?). Also it would be great if you could point me towards some small issues/bugs related to this topic so that I can submit a patch and show you guys that I will be able to do this. P.S. - I'll be there on IRC at #haiku with the nick ana_s Thanks, Anshul
