Owners, and moderators with the appropriate permissions, can edit the properties of topics that have already been posted to the archive on the group’s website. The changes they can make are:

• Edit the subject line of the topic.
• Add hashtags to or remove hashtags from the topic.
• Moderate or unmoderate the topic.
• Lock or unlock the topic.
• Make the topic sticky or unsticky. (Sticky topics are pinned to the top of the Topics page in the message archive.)
• Change the Reply To setting for that topic.
  Note: If you change it to Reply to topic followers only, the system automatically sets up follow topic records for the person who started the topic as well as everyone who replied to it. Those people then will see an Unfollow Topic link in the footer of subsequent email messages in that topic.

You can use any of these methods to edit the properties of topics in the archive:

• In Topics view or Messages view, click or tap the down arrow button next to the posting date, and select the desired option from the menu that appears.
  Note:
  • The menu contains more options in Topics view than it does in Messages view.
  • If you select Lock Topic from the menu and your group has an active Locked Topic notice set up, that notice is sent to the group automatically.
• Open the topic on the website. Then click or tap the More icon at the lower right and select the desired option from the menu that appears.
  Note:
  • You cannot edit the subject line or change the Reply To setting from that menu. But you can make those changes by selecting Topic Properties from the menu.
  • If you select Lock Topic from the menu and your group has an active Locked Topic notice set up, that notice is sent to the group automatically.
• Open the topic on the website. Then click or tap the Topic Properties button at the top of the page, or click or tap the More icon at the lower right under the message and select Topic Properties. On the page that appears, you can change any of the properties listed above (you can also delete the topic). Click or tap the Update button when you are done.
  Note: When you select the Locked checkbox on the Topic Properties page, a dropdown list appears from which you can select a Locked Topic notice that will be sent to the group after you update the topic’s properties.
