we are testing IPB 2.3.0 with IP.Converge 1.0.0 PB 2 (Zend Version).
We have a problem on user registration. We set users must validate its registration with email, but email is blank.
We test to send an email for password recovery, but this work good.

We are also developing an interface to IP.Converge for our applications... if someone need some help can download it from http://test.teamplay.it/ipb.converge.test.rar to have a little first interface to converge system. This code require php with xmlrpc-epi module built in ( http://it.php.net/xmlrpc ).

emmm... another problem found....
if administrator delete a converge account IPB2.3.0 doens't recognize correctly the ipConverge.onMemberDelete call. We hope user must logged out automaticcaly and we hope is necessary to drop any users information on IPB database.

Please wait for the next beta release of converge - dozens of changes have been made, and I know at least the first issue you mentioned is fixed.
