I got the screenshots program installed as you can see from the screenshot in my last post. But I got instability after that so uninstalled it. I probably bumped up against a low limit set on the size of the applications folder which I've read about.
You can create your own applications folder without a size cap but I want to be a little careful altering the plumbing when I'm still such a newbie with this stuff.
I did get Transmit on my Mac to connect wirelessly to my iPod touch. That is cool stuff. A tip I read said to access via SFTP instead of regular old FTP. That did the trick.
