Three problems with Events module

I set up the Events module for my install using the latest UNA and was configuring everything. There are three problems with the module.

Problem #1: Commenting on group events is not possible unless the event creator creates an initial post. With profile events, anyone who is attending can post and comment. Commenting is an internal option in Pages, but it is turned off. If you turn it on, it just hangs on the event page and doesn't work. Here is a screenshot:

Problem #2: The Questionnaire option is unfinished. The event creator can start and edit a question, but it is not accessible to any other event attendees.

Problem #3: The event sub-menu item "Groups" does not get utilized. I just turned it off.
