I think that for most posts, markdown is fine. It's just the same as using a wordprocessor, besides using underscores and asteriks for emphasis. For cases where you need lists or headings, those are just slightly more complicated.

Maybe we just need a markdown syntax cheat sheet? On the other hand, I guess it would be nice if we offered something like the FCK editor as an option. I know one killer feature that I personally miss is a spell checker.

I'd be willing to get the FCK editor into Typo trunk when I have some free time in the next week or so. What do others think about this course of action?

I think it depends on your target audience. For you and me, markdown is fine. Its fairly simple.

For most people though, I think markdown is asking a bit much. Even this trac wiki, for example, has a toolbar to help users put in the correct markup.

The counter argument is that anyone setting up a typo blog is technically savvy. But then again, I setup a WordPress for my wife who is not technially savvy - all she has to do is use it. Or, people could use typo blogs hosted by some 3rd party provider.

So - it all depends on what audience you want typo to reach.

I requested this feature in scott's blog as well. FCKEditor should be a good solution for this. Here is a link that can probably be followed to achieve this.

There should definitely be a button/option to enable the editor. This is a major lacking in Typo currently.

A WYSIWYG editor was included in Typo long ago
