BuddyPress.org

I had S2Member extension install on buddy press, I did a sandbox checkout with PayPal, and return to user registration page once the payment method is complete, BuddyPress then send me email confirmation with activate key.
Here is the problem:
I accidentally closed the page before the confirmation URL loads, then I try to copy & paste the URL to an other browser, it says “invalid” activation key.

i know this is a stupid mistake, I ended up have to re-purchase the membership again, I just thought if we can have a button on “Invalid Key” page, so we can resent a new confirmation email.

Can any1 point me a direction where I might be looking into?

I will share the result if I find anything useful.

Regards

Gary
