1- This is a commercial script, it won't be free for download.
2- I don't have a definitive answer to this at this point, I think TinyMCE, for now, will do fine, a rewrite might be in the pipes for the future; but i can't find the post where this was said, so can't confirm.
There is no ETA on the download, consider it "not very soon" and more like "Q3-Q4 2010".
We are at a site with only a community, and no company information pages.
The build is the first or second alpha, very early and not near finalized.
Details such as availability and pricing are undetermined.
When available, they will be published in an announcement forum or on their company blog or frontpage.
I'm now convinced that this is the best forum software I've ever used, and it's in Alpha. With it being this advanced right now I'm expecting Gold to have a CMS, articles, static pages, widgets a front page and lots of other cool stuff
