Coinschedule just lists ICOs that are out there. We aggregate and organise information that already exists irrespective of Coinschedule.
Similarly, we don't receive money from users and we don't pay, store or transmit any funds to the ICOs.
In order to join an ICO, users must visit the ICO's web page and follow the instructions presented by the ICO. Please note that every ICO may have different rules and procedures for joining, so it's important that you assess each ICO carefully before sending funds anywhere.
