"I hoping to compare the ionic to the Pro v5 series"
Have you gone to the link that Gerry provided and compared the two? What features do you want? How much are you willing to pay? Hobby or business? Etc. What sort of projects do you want to make? Contact Axiom and check with sales and hear what they have to say?
Bob, Use the full-featured Reply function available when you are logged in (red button above-right on Reply box). There are 10 colored icons on the right side of the Create Post box that opens, the left-most of these (a globe with a piece of paper) is the insert link feature. Just hover your mouse over the icons for their descriptions. It should be fairly obvious how to use the feature once you've found it. There is another icon almost exactly like it for "Gallery" (second from the right). Sort of stupid design to have two different features with the same icon, but it is what it is.
