The invitation code is a special pass when registering. The invitation code is equivalent to entering the registration code with a software. This is the role of invitation in real life. Only after receiving the invitation code can you register your account.

Each invitation code can only be used once, and the validity period usually ranges from a few days to dozens of days. After the expiration, it can no longer be used for registration and must be re-applied.

Each forum has different regulations on the authority, purchase time interval and purchase price of invitation codes for members.
