Naples Community Calender by Florida Weekly
Founder of this Naples site of NeighborHelp Referrals.
Very descriptive calendar of "What to do, where to go" in Naples
NOTE: On some browsers, you will have to add a "slash" at the end of the URL if it says "Document not found". This isn't a problem of naplesplus, but rather the floridaweekly site. I believe they are working on the problem.
So, in the end, it should say "http://naples.floridaweekly.com/Current/Community_Calendar/" with the slash / at the end. Then the page will show up.
