Absolutely! I am going to send you to the Holy Grail of HP knowledge.
Go to http://hubpages.com/@learningcenter
There are tutorials on every aspect of hubbing. Including a handy section titled "How to post your first hub" (or similar).
The main thing you should know is that this is not a blogging site. You don't "post blogs" to your hub page. You write hubs. They are independent articles. Take a look around and visit other hubs and other hubbers and you;ll soon get the hang of it.
Trust me -- if I can do it, you can!
