Which RTE for Revo?

Do we know for sure what the default Rich Text editor will be in Revo?

There likely won’t be a default as part of the core standalone distro, as it’s an add-on/extra. The first one developed for it though will almost certainly be TinyMCE.

Distributing a CM(S/F) with no built-in RTE? It seems like a marketing mistake, IMHO, no matter how easy it is to install the add-on editor.

Content/feature packs are a completely separate bit from the core distribution. Separating the two things is designed to avoid having confused users thinking MODx is to blame in the event a third party add-on creates a security problem.
