Hey Jeff. Thanks for your interest here; while some users have been able to make such integration work without issues, others have reported problems depending on their specific setup. We haven’t done any testing on our end against Buddypress for Events Calendar PRO or the add-ons but do have plans to ease integration in a more official capacity sometime during the 2.1 lifecycle. Apologies that I couldn’t offer up more in the interim.
Thanks again for your interest and please let me know if you have other questions.
