Hi Jane, welcome to wetcanvas.
This is a terrific community and a wonderful resource, there are forums for just about every art and craft medium here, here's a full list of the forums.
As you are interested in watercolors I suggest you check out the Watercolor Forum
The links in my signature will help with the forum and give links to lots of demos, articles, videos and free on-line tutorials. If you have a particular site problem, click on my name and send me a private message (pm).
There are many talented and generous artists in the forum who will love to share your art.
Introduce yourself in the "Daily Wash" in the Palette Talk forum - they are a great bunch of folks.
I look forward to seeing some of your work in the Watercolor Gallery, or in the Watercolor Studio if you need advice. Technical questions are asked in the Learning Zone.
There is a thread at the top of the watercolor Gallery showing how to resize and post your pictures.
