Hi Kevin,
Thanks for the compliment! So let’s take those one by oneā¦
1) Community Events works just fine with The Events Calendar (free). Adding the PRO license will get you some additional features though. Up to you.
2) We do use the Events slug as part of our plugin, so that sounds like some good preventative medicine there to change it to something different before installing.
3) The iCal import function is available on several views. At the current time subscribing to a calendar’s RSS feed isn’t possible, but you’re not the first to mention it. If you’d like to throw your hat in the ring, you can see the discussion over at https://tribe.uservoice.com/forums/195723-feature-ideas/suggestions/3777092-enable-calendar-synchronisation
I hope that answered your questions. If you have any more, please ask!
