I have found some old threads mentioning that this is not possible, but am trying to import a large amount of member data for a client, and am getting email not valid errors because they contain apostrophes, and am wondering where you are on this…
While programmatically i can appreciate the difficulties, you are a large commercial CMS and i would have thought it a necessity to match up with email standards whereby apostrophes are allowed
A large contingency of Ireland i am sure would agree!
