Thanks for letting me know. Your post was automatically got status ‘Pending’ due to 3 links inside and I missed it. I published it now.

I need access to the membership plugin to look how to hide its “Select member type” drop-down menu. Is your membership plugin available at the wordpress.org/plugins? Send to support[at-sign]role-edito.com a direct link to it (at wordpress.org or to your own copy via DropBox or similar sevice).
