When you post from the Travelfeed front end you can choose which Hive community you want to post in. Think of Travelfeed as a door, going into a house (Hive) and the communities on Hive as different rooms in the house. You should match your post to the correct community for maximum support.

Also, a little tip for you to build your network on Hive. When you go into a Adidas shop, you wouldn't shout "Hello Nike friends, I love Nike and I want to tell you about their fantastic products that I use everyday. I want to thank Nike for telling me about them"

Hive is a big community and can be quite confusing for new joiners, but it's really quite simple once you get used to it. Some people like to stay in their little world and make post because they enjoy doing that. Others like to extend their reach a build a network. It's as big or small as you want it to be
