CloseReview for Flexible Identity by B. S.
Rated 1 out of 5 stars
Sadly there is no documentation except for this add on page. So really can't use this. Sorry.
In particular, how to fill out the filters text box is a complete mystery.
A developer web page with terse documentation / hints would be useful.
