I'm working on a project for a foundation that manages a number of microsites and a few regular websites. Right now the microsites are just WYSIWYG HTML pages and the main site is managed by one CMS tool, Convio. We want to bring all these together under one roof. I'm most familiar with Drupal however I think a CMS that has an easier admin area would be best (and maybe an easier theming method). If any have a great WYSIWYG tool, that would be preferable -- I will likely do all the coding but most of the users here need an easier way to input content.
Any recommendations? Maybe ModX? I'm not sure.
