A way for others to be able to by a membership for someone. Maybe a way that, they are given a code that can be given to someone (be it someone they know or someone random in a forums or live chat). The new person can then take that code to the membership portal where there could be an option to claim the membership. The new member would then have full access for however long the terms are for that membership till it expires, where they can then either let it expire or give payment info to continue for renew.
