I tend to go back and forth. Overall I like the old editor better, but the new one has it's advantages too. Feel free to let me know when you use the old editor and have a broken formatted page without using the new editor to fix it. I usually spot those issues in a jiffy.
I would then be able to explain what went wrong.
I'm not familiar with EPiServer CMS, but I signed up to get a free demo for it. Unless it's scary priced, I don't think that will be an issue if it's both fairly easy to integrate into SummitPost and is proven to be beneficial. I'm trying to cook up some ideas for SP version 4 for this up coming Fall. I'd also like to see a re-done private message system which I plan on doing an investigation on that. It would also be nifty to be able to select the default editor in the profile.
Look what you did, now you got me saying a bunch of stuff that isn't related to bug fixes.
I plan on having a thread dedicated to this kind of stuff in a few months.
