Our public site is done in Word Press, and we are going live next week with CRM 2011 online (just completed the Update 2012). We are in the process of developing custom modules for event registration, invoicing / account management, new membership sales, communications profile and membership directory. Rather than invent these integrations from scratch, I was hopeful that someone had already done this based on the popularity of both platforms.
If anyone has any experience to share, I would appreciate it.
