I'm in the middle of building a site on Memberium and I have to say, the whole experience has been so much better than I could ever have imagined. First off, I have to give a massive shout out to the support team at Memberium - they are phenomenal! They respond so quickly (even though I'm in a totally different time zone) and they are always helpful, knowledgeable and incredibly patient. Because this is all new to me, I invariably come up against challenges or problems, but they never make me feel like I'm being a nuisance.
The plugin itself is awesome - superb templates with everything I could possibly need to build my site, and seamless integration with Infusionsoft. I'm a massive fan - thank you to everyone at Memberium for a brilliant product with awesome support!
