I like that it's easy to use, has many features, can be customized with plugins, etc. It does not have any downsides for me. That being said, there are some things about this software that could probably be improved upon. For example, I would like to see more tutorials available online that teach you how to customize your own pages in order to make them look just as good or better than those of other websites out there. There aren't really any cons at all that I can think of. If you're looking for an open source CMS (content management system), then you should definitely consider using php nuke. We've been able to easily create new website designs without having to hire expensive designers. Also, we were able to change our old site into something much nicer by simply editing one page. This also allowed us to add additional functionality such as blogs, forums,.
