I am looking for some help on a small project for my site. I haven't created anything yet but what I would like is a simple email form (which I could create) But I would like it to have a section with 10 lines where you can input 10 email addresses. Upon entering the emails, once submitted, it would send them a pre-designed email, inputting informations put into the form initially. For example: It could be a party invitation You fill in host name, date of even, time, place, and 10 email addresses It sends a pre-designed "invitation" to the 10 email recipients, inserting the host name, date, time etc in the email body where i would preset it to go. Is this simple? Or is it difficult, requiring mysql etc. Can anyone point me in the right direction? Thanks!
