Hey, I actually hacked in the Tcl Wiki code into ETP. Get it: http://www.thedesignexperience.org/etp-wiki.tar.gz Its not perfect yet, but should give some ideas.
Now necessarily a wiki. Just an easier simplified UI for adding content and pages. ETP will still use the openacs traditional access controls.
Use General Comments with an inline form (optional, but a nice idea). Expand richtext widget with formatting options similar to wiki syntax.
Here is some wiki formatting instructions to keep in mind:
Editing Hints:
Just type your text, leaving blank lines between paragraphs.
You can use Cut, Copy and Paste from your browser's Edit menu (or their keyboard equivalents) to move text around, copy it in from other documents, etc.
Add links:
* You can link to other pages in this group by enclosing their name in square brackets, e.g. [Help] => Help
* Link to other web pages by just typing their address, e.g. http://www.yahoo.com => http://www.yahoo.com
* Make an email link by prefacing it with "mailto:", e.g. mailto:x@y.com => mailto:x@y.com
To get fancy:
* For bullet lists, start each point with a "*", and type the entire point on a single line
* For numbered lists, do the same but starting with a "#"
* Use four or more dashes alone on a line to create a separator
* Use a single dash alone on a line to create a line break
* Surround a heading with three asterisks ("*** Heading ***"), all on one line
* Use three single quotes for bold: '''bold''' => bold
* Use two single quotes for italic: ''italic'' => italic
* To preserve spacing and breaks, start and end a pre-formatted block with three "="
