许可协议
开放源码并不总是意味着免费。有些许可协议允许非商业用途免费使用软件，其它（如GPL）是免费的但是需要标识源版权。否则，必须购买许可。衡量一下你的应用程序，再选择符合需求的最划算的那个。
在评估使用哪个工具时，也要考虑该CMS是如何使用的以及最终用户是谁。CMS的使用方式是关键，它决定了如何根据基本的许可协议来使用该CMS。
支持
拥有多种支持手段是开源产品的一大特色。例如，PHPNuke和它的派生产品没有商业支持，但是用户和开发者的联系是如此广泛，因此社区的支持相当可靠。但是，项目工程的特点及其安装需还是要更多传统的支持，比如基于事件的故障对策。
我建议你考察一下支持的方式并确信它们是适合你的。不管你选择哪个CMS，总是有可能出现某些故障的。除非你自己能够调试代码，要不然支持对于你的实施来讲都是至关重要的。
