What if I cancel my alias?

By giving up your alias, you make it free for other users, who can start using it. However, you should bear in mind the possible problems stemming from any alias change. That is, provided you have made your e-mail address public in the form of brandejs@mail.ambis.cz and now you decide to change your alias, people will start sending you messages either to a non-existent address or to someone else's (a similar situation has been described in the previous paragraph). It is therefore advisable to create an alias that you do not plan to use only for a short time.
