The calendar function is terrible: there is no support for recurring events and sometimes, events disappear. Once when daylight saving time hit, every event was off by one hour. I found out later there was "a script that could be run to correct this," but had already taken the time to manually update each event.
Support is responsive and as helpful as they can be, but a bit too often, the answer is, "I'm sorry but that isn't possible."
Daily email digest function is VERY limited and lacks customization options.
No ability to set pages to *not* expire (other than setting the expire date to the year 2099).
There is a customer portal/site where customers can submit ideas and suggest features. Some very popular suggestions have been acknowledged, but remain unimplemented 4-5 years later.
