First of all......get chatty!

You need at least 10 comments into the forums before you will be able to edit your pictures or comment on pics in the gallery.

Just jump in with both feet.
Next....if you want to participate in challenges or just need some inspiration ~ hop on over to the challenge portfolio
thread. I print off the challenges so I can keep track and also so I can refer to them later for inspiration.

At the beginning of the post that Robin puts up there is a link to a PDF file to print off.

The basics about the challenges is that you can earn points which earns you a discount (sweet rewards) in the shoppe. Your discount can be 20-40% off your order depending on how many points you have earned.
Once you have had a chance to look over the challenges, then PM or message me to ask more specific questions. I don't want to overwhelm you.
