Here the update I promised in the last post.

Changes:

• when checking for already registered member there is now an additional phrase for distinguishing between registered and invited members (reqested by Alfa1)
• added on option to display the invitation code as a link again (requested by Alfa1)
• remove the "click two times" message from the invitation email phrase. That's not needed anymore.
• changed "mysql_real_escape_string" to "$db->escape_string"

Please test before including in the next official version of this mod

What's missing is a cron job that deletes pending invites after x number of days automatically and gives the intivations back to the users. This should help users who cannot delete sent invitations that were never claimed or sent them to a wrong emal address. This should be combined with optional features like "give additional invites ever xxx posts" or so.
