I am a fan of WP Wishlist Member and I have found a lot of great uses for the WordPress Membership Plugin that are beyond the obvious, which is doing a membership site that makes money.  So here are some alternative usages for whishlist member – if you buy the multi-site license you then have the tool (along with wordpress) to crank out private membership sites all day long.

1. Private Sales Portal – Use Wishlist Member to create a private sales portal for your sales team or for your affiliates.
2. Course – You can develop a one time course using WP Wishlist Member.  It does not have to be a monthly thing – and you can later upsell items as they stay involved in the course.
3. Intranet – WP Wishlist Member is a great way to create a simple intranet for your organization.
4. Upsell – I use Wishlist Member to manage a free membership site – but the free site is not open to the public, it is an upsell for another product where the customers that join via my reseller account get bonus training.

I am sure there are even more uses for Wishlist member that you can think of.  Feel free to leave ideas in the comments area.
