I added a Notes section (User's Guide would be a better name) to Marybel's page. I tried it to make it as "neutral" as possible My idea is many users (including me) fail to grasp the true potential of some units so having Notes (or User's guide) section for those units would be nice. IMHO this does not belong to the comments section since comments get buried quite quickly. Best would have been to make it a collapseable section but did not find how.
Thinking about a it the best would probably to have a "Unit usage guide" and having links pointing to the unit's usage page in the Uni's page: Having usage notes buried by comments on how sexy is the unit is not good and since those notes can be lengthy they deserve their own page.
