Well, yes, in fact it is!

Promote gives you an easy way to add a button or a sign-up box to your web page to encourage new members to join your group. The button takes new members to your group’s main page. The subscription box subscribes a member to your group and sends them an email confirmation.

To use either one, just click Promote on the left side of your page. This opens a page containing HTML code for both the button and the subscription box. Just copy and paste whatever code you like onto your web page.

Group owners can restrict access to this feature. Here’s how:

1. From the list on the left, click Management.
2. In "Group Settings," click Web Tools.
3. Next to "Web Tools," click Edit.
4. Scroll down to "Promote" and select Members, Moderators Only or Off to adjust access.
5. Click Save Changes. Done!
