Hi Daedalon,
Unfortunately I had to stop using the plugin and find other means so I am not at this time able to test the update (we have just published our third website based on wordpress and have an aveage of 150 visitors/2 registrations per day – if we’d continued using the plugin none of this would have happened as it is necessary for people to register to review large parts of our content).
Our current solution, which is using the registration module from gravity forms is adequate but not especially comprehensive and we may look to rejuvinate the system at some point in the future (talking months rather than weeks). At this time I will be sure to feed back on the compatibility of the latest version.
joniborm – thank you for your response unfortunately back in February when I started this thread I had just upgraded to the latest version of WP (a noob error as I should have tested compatibility with my modules first in a dev version but this was my first use of wordpress) the latest pie-register version was not compatibile with WP 3.3 and whilst I waited for over 2 weeks for a fix nothing appeared – I had to move on as I am working on commercial projects.
