To register on Ecobilda, we need your email address to confirm your account. This information is not available to other users. However, if you publish an event, you will have to provide us with a telephone number, allowing the ecobilda team or, depending on the cases, your event's participants, to contact if needed. Your email address, in this case, is available to your event's participants. Finally, if you list your professional activity, you need to provide your full company's or organisation's contact details.
