Hi, -Starting with a PHP 'contact us' form (currently works). -I want to inform users they are opting into a mailing list, and have "the message received into the proper database", instead of going to 'admin@thisdomain.com'. What is a good basic (free, open-source) mailing list program and how do I 'merge' the current 'contact us' form w/ the mailing list? Is one solution as easy as just sending mail to (for example) 'listme@gemini.com'? Thank you
