No. Certainly not against it but I already have a snagit license. One of the big things I like in snagit is the picture manager that basically "ingests" all the captures in a row. I can then go back and mark them up and do a mass copy and paste in word / the web / whatever and it will inject them all which then leads to an easy way to do descriptive text.
It is really handy for a manual the explains Outlook Rules or some other thing as I can keep capturing the windows after each step with a single button press. Add arrows and annotations, then plop them all in to word as a large group.
