It is very easy to use, even for beginners! I am using it now since almost 2 years ago (it's still my favorite CMS) but there are so many new features that you can't miss out when upgrading from older versions of semplinse club or if your website already uses this platform as backend solution like we do in our case :) There were no problems at all during those two year period which makes me trust more into its stability than other platforms i have used before - sometimes things break down though after update/upgrade. We created an online shop where users could buy products without contacting us directly by email etc., via their own webshop account they would be able store several items within one order / user profile.
