We have released the new version 1.6 of Members Only (all editions), which includes two frequently asked features as control of log-in redirection and custom fields for invitation request form.
New Features in Version 1.6
Login redirection - Regardless of your site's settings, now you can set the Members Only plugin to redirect users to certain page immediately after they log in.
Custom fields - If you require extra fields in the invitation form to know who or why is somebody asking for an invitation, now you can build your own request form and Members Only will send you the extra fields information in the notification email.
We have tested this new version in Joomla! 2.5.
