Allow users to login with email address not username
We have been asked a number of times if it is possible for users/members of an OptimizeMember site to login using their email address and not their username. They can certainly do this, but please read on for more details.
When using OptimizeMember built in payment gateways:
OptimizeMember does not provide this functionality as standard when using the built in payment gateways, and we have no plans to add this currently.

Currently, OptimizeMember will allow setting the username as the email when using the OptimizeMember API system (found under "OptimizeMember > API Scripting > API for remote operations" - in this case setting the username to be the email is recommended.
