Sharing worksheets.

Hello, everybody. A friend of mine would like me to share with her a set of private liveworksheets I have created so that she can make some changes to them in order to customise them for her students. I have no problems sharing my private worksheets with her, but I don't know how to do it. The idea is that she can edit them as she pleases and she is able to have them in her liveworksheets account. Do you know if this is possible, if so, how can I do it? Thanks in advance!
