We went live with out Intranet today 
All went fairly smoothly but we can seem to get comments to show up unless you enter _nocache.
I've set the comment asset type in the cache manger to not to cache but when a user leaves a comment it does not show even if they return a hour or so later, the only way is the _nocache
anyone care to comment(!) :blink:
If your comments are being nested into another asset type (like via a Paint Layout), you should change the cache timeout on that asset type instead. Also, check that you're not caching the Body design area in your Design parsefile.
