If you're a member or administrator of a group, you can share content in the group stream on the Activity tab. Group administrators can remove group posts at their discretion.

If your post has been removed, contact the group administrator. The founders of each group decide what is considered appropriate content in the group. 

If you add a new event, image, or photo to a group, it may not immediately appear in the group's stream. This is because the group administrator has enabled a setting that allows administrators to review the posting before images or scheduled events are shared with other group members. If an administrator rejects your post, it will not appear in the stream and you will not receive any notification of the rejection.

We encourage members to post content that is relevant and unique to the group. If members post the same content in different groups, the post may be automatically marked as spam and not displayed to group members.

You can add comments on the Group Activity tab or anywhere you see the Comments link.
