# Members and guests settings

# Members sign in and invitations

Administrators of a team or organization have the responsibility of defining how a member can sign in and who can invite him.

In the **General** tab accessible through the **gear** icon at the top of the left-hand navigation menu, verify settings for members sign in :

* **Allow members to sign in** let users sign in without being invited
* **You should add an email domain restriction** to be sure that only members with these emails domains will be able to sign in without being invited

* You can **allow members to invite other members**
* You can also add a constraint to be sure members can invite other members only if their email domain follow the same rule as for sign in.
