The best way to start on HubPages is by doing the following:
1. Allot time to read the Help Page or Tutorial Pages. Knowing formatting and the buttons to click makes writing so much easier and give you a certain target of readers and followers.
2. When you read a hub, act on it either by voting or commenting or both.
3. Follow hubbers you like.
4. Participate in everything on Hubpages -- Answer, Forums, Hubs
5. Write what you are knowledgeable about. Read to expand your knowledge.
I hope this helps and welcome to HubPages!
