The 1150 can only display .imp files. The ebooksystem server at
https://my.ebooksystem.net/personal/default.asp (note that the www. is not needed) can create .imp files from a .txt file and download it onto the 1150.
I'm not sure but I think that's the server my 2150 talks to when I hit online bookshelf.
Right now, I get an error when I try to upload a file but the 2150 can see the server. I can't find the 1150 which bothers me so I'm hitting submit for now and going on a treasure hunt.
I found it! And the big one is a REB1200, not a GEB2150. I get so confused...
