Hi Rick and

What you have there is a pic of a new growth coming up. (new cane)
As for posting pics, you'll be able to as soon as you get 5 posts placed on the forum
Again welcome!
There are many members here that would love to meet you and hear about your orchids. We love pics too.
You can introduce yourself in the introductory section of the forum.
Also it would be great if you could go to your profile and update your location as members here are from around the world, and if you ever need advice, different locations = different advice.
