Previously, I set up a contact form for my upcoming Cassette Beasts fanlisting with InfinityFree's PHPMailer contact form code. Now, I finally succeed in implementing PHPMailer into all the fanlisting's functions that involve sending out emails, such as emailing new members after they submit the join form and when they get approved, as well as emailing me when a new member applies to join the fanlisitng or when an existing member updates their member details.
Furthermore, I managed to add the rest of the features of BellaBuffs' contact form, such as spam detection, into the Cassette Beasts fanlisting's contact form as well.
