I am so sorry, I cannot answer that for you!  I have looked and looked and looked, there is no user guide other than TOS and image size max if you accompany your work with one.

It would seem logical to have a posted user guide like the others do.  I did read something that was posted in '03 when they kicked off the writers gallery,  that mentioned a 15,000 word limit??  That was in the comments, so I really  I don't know.

Can someone help?? I am very interested too!

Namaste...it's universal  [ =
