Welcome chris, from Ontario.
You'll get the hang of forum navigation quickly
.... moslty because you'll spend most of you time not riding on here
To post pics, when you hit "reply" and the "post reply" page loads, to the bottom left of the typing box it says "+ Additional Options...". Click that and browse and attach your pics there. They need to be a smaller size so you might need to compress them a bit first.
Also, check out the FAQ section: click here:
