Hello Bubblers! 
I have set up a simple 2way SMS via Twilio on my site but I do not have the proper database set up. A user can SMS a nonuser (nonuser supplied their phone number). A nonuser can then SMS back to that user. Other Users can also SMS that same nonuser. All User phone numbers will be the same number (supplied by Twilio). What is the best way to create the DB structure?
Thanks all!!!
