It is opensource.Xenforo wanted CKEditor .. but backed out when it had bugs. CKEditor is not Open Source.
Yeah, why not?If its that big of an issue... I am certain 10 people throwing in $50 to get that accomplished would not be a problem at all. Hehe.
After playing around with Redactor I would love for xF to ship with this. I think it would make xF that much ahead of everyone else. The inline image resize that melbo mentioned is freaking awesome.
They have interesting plugins, http://imperavi.com/redactor/docs/plugins/:
The "fullscreen" mode is now a plugin on the toolbar to toggle full-window editing on and off.
Adds a drop-down list of pre-defined "clips" (or "snips") that you can create to save time, such as intro or footer text.
Very interesting, as I was always looking for my Mods to have ready-made text-snippets for them, so that they can just press a dropdown and select a canned response to yet again a member who is posting unwanted advertisements. Clips like that would come in soooo handy, making life on the forum for my Mods considerably easier and fun.
