# Restrict permissions of new members {!admin-only.md!} In large Zulips where [anyone can join](/help/allow-anyone-to-join-without-an-invitation), it can be useful to restrict what new members can do, to make it easier to cope with spammers and confused users. Members are **new members** from when they join till when their account ages past a certain **waiting period** threshold. After that they are **full members**. You can configure how long the waiting period is, as well as which actions require being a full member. Currently, the following actions support limiting access to full members. - [Creating streams](/help/configure-who-can-create-streams) - [Adding users to streams](/help/configure-who-can-invite-to-streams) ### Set waiting period for new members {start_tabs} {settings_tab|organization-permissions} 2. Under **Other permissions**, configure **Waiting period before new members turn into full members**. {!save-changes.md!} {end_tabs}
