<h3>What is the difference between group and a topic ?</h3>
<h3>Group</h3>
- You can publish a comment or question to the main community feed or to a group of which you are a member. Members with a common interest can form group within the wider community to form a small community around that topic and group posts will only appear in the feeds of other group members, not in the general community feed.
<h3>Topic</h3>
- Topic work similarly to hashtags. Use the "+" symbol to the left of the Post/Ask button to add a topic (tag) to your post or question so that it can be classified along with other related posts and topics are a way to group posts and queries with similar content, but they don’t bring everyone with the same interest together in one place and this is where the groups come in!
