Jenny/Dan:
What types of content do anticipate having in the Documentation Toolkit tab? Here's an example of what we have on LEEDuser:
https://leeduser.buildinggreen.com/credit/EBOM-2009/SSc5#tab-docs (login required)
The layout is a little complicated on LEEDuser, since we had to work with a lot of legacy content, but since we're starting fresh on BITuser I'm hoping to simplify the design. So it would help to know what types of content you expect to provide.
