I found just one post on the Xbag. I checked the posters lists and she hasn't posted since January so she may not be checking in lately. She was going to do a tutorial on it but I didn't look through all her posts to see if she did.
http://www.quiltingboard.com/t-1497-1.htm . You can click on her user name. Then click on the topics posted list and see if you see it. Then you can click on the updates she made on other posts in case she mentions it in another post. Sorry I couldn't be more help.
