use 'https://my.phorest.com/a/46267/clients/create' to come up with a way clients can add to a 'mail list' which basically creates there own client card and adds in their details so we can capture potential clients, send promotions/ e-mail sms market to them etc. (our own version of lead generation)

PLEASE add a way clients can add in promo codes so we can send special discounts to clients via e-mail marketing for Black Friday, and holidays. also somewhere they can book there treatment online using their gift voucher codes!!!!
