These are some improvements on the existing code, @aalvarado how do you feel about the following:

1. Getting rid of wymeditor and storing html altogether
2. Removing jquery-ui
3. Add bootstrap-sass
4. Switch to markdown
5. Add user invitations
6. Bring back RBAC
7. Replace paperclip with carrierwave

@EnriqueVidal Will the cms be for ourselves only, or is this something we are going to offer to clients as well?

[EnriqueVidal]

I think both, the idea behind invitations is to delegate tasks to other users.

[aalvarado]

got it. Everything seems like we need it. I like where this is going. 👍
