If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
When you say opt-ins are you referring to having people sign up for a mailing list? If so, check out this tutorial to see if it will suit your needs. Please let me know if I have misunderstood your question.
