I am working on updating the existing TinyMCE editor on Geekzone to a newer version that's faster, CDN friendly and a more modern look.

Being CDN friendly means loading the editor when creating a new topic or sending PMs will also be a lot faster (my own tests shows it is).
I am still coding around to see how it behaves but hope to get this done and ready for some testing later this week.
If you want to give a try later and win the Beta Tester badge, reply here.
