Hi, Kostas. Thanks for your interest in our plugin suite.
The information you use to register your account and make your purchase is where the receipt will be sent. You may also change it at anytime at https://theeventscalendar.com/my-account/
After you get the emailed receipt, feel free to open a new support thread (while logged into your new account) to ask for anything additional you may need and we’ll do our best to assist you.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
