I always wonder how people expect us to match up a different PayPal email address for payment to a different email address that is registered on the boards! LOL
That is why we like to have people fill out the JOIN form so we can try and match the names. That is, unless the PayPal is from Sally's Floral Shop and does not match the name on the JOIN form.
Once the PayPal has been processed (not automatically, may take 2-3 weeks) we send an email asking for the correct email address and board user name back to the PayPal email address.
Only thing harder to process is a mailed in payment from "Bob" with no email address and no return address. I'm always wondering what that guy is trying to join! LOL
It is also hard to give membership access to people who have not registered on the board. You gotta really wonder what they are joining. Also tough if you have NO email address!
