With the vast amount of work going into the Knowledge Centre (hurrah!!), I'm checking it regularly.
The only catch is that although the date changes on the Welcome page to indicate that it's been updated, there doesn't seem to be a way to know where to look for the additions.
For instance I only stumbled on the fantastic CobraNet Appendix cunningly hidden in the NION Hardware Manual.
However, if you have to choose between documenting the updates and continuing to write them, please ignore this post!!

For the next release, I will aim to include a "What's new in the Knowledge Center?" link on the front page. Clicking this will display links to the manuals / main sections that have been updated.
