Registration Tips and FAQs

If you are registering for one of our conferences or workshops, please note the following:

  1. Payments must be made online using a credit card. We cannot accept bank transfers or cash payments.
    • If your institution can only do bank transfer, we recommend paying with a personal card and requesting reimbursement from your institution.
    • If you have trouble with your card being declined, please check any restrictions on the card and that all billing address information was entered correctly. If it still won't go through, please try a different card or call your card issuer. Unfortunately we cannot diagnose reasons for cards being declined on our end.
  2. Visa invitation letters for in-person events.
    • Registering and submitting payment does NOT guarantee you an invitation letter.
    • If you are attending a conference, you must have either an approved abstract or contact us with a scientific justification for attending the conference. The justification should include a brief description on how you use the model in your research.
    • If you register first without these requirements and wish to cancel for a refund, you are subject to a $50 USD processing fee.
  3. Refunds.
    • Check your event page or registration form for the final date by which you may cancel and request a refund. No refunds will be issued after this date.
    • All approved refunds are subject to a $50 USD processing fee.
  4. Invoices.
    • Payment invoices will be issued after you register. Please allow up to 5-7 business days before contacting us for an invoice. Invoice will be sent in PDF. 
    • If you need to add VAT or any other billing information to your invoice, please contact us. Note that we are based in the United States and do not have our own VAT.
    • We ask you double-check your institution payment requirements before requesting an invoice be issued before submitting payment. Often this requirement is for bank transfers, which we cannot do.
  5. Contact us.
    • For all other questions or concerns, please contact eco.web@tamu.edu. We ask that you please also add this email to your safe-senders list and check your spam folders for any missing messages.
    • Please do NOT email the marketplace email address from the registration form itself. We use a central payment system issued by Texas A&M University, and their general email cannot assist you. Contact the email address above instead.
