Using Wild Apricot (WA) to build a functional site for small, community based non-profit organization. This is a good system for those with a (very) limited budget, who need a basic member management solution. While there is a free version, it is only suitable for the most basic functions (ie: limited contact capacity, no recurring payments). At that point, if "Free" is still the primary driver, you'd probably be better served using one of the other popular CMS platforms (WordPress, Weebly, etc...) to have more creative flexibility.
