I've started putting metadata on my kits, too. I have a template saved in Bridge for commercial use and one for personal use, so all I have to do is select all the kit files, right click, select File Info, and choose the template I want. And voila, my name is on every file! I love it. Great tip!!
Also, I wanted to point out something I just discovered -- the Mozilla Firefox web browser does not restrict the number of files you can download, the way Internet Explorer does! So if you have a high-speed internet and want to just click to download and walk away, you can click each file one by one, it loads them into a little downloader, and you can leave it there. I downloaded 13 files at once the other day, from the same store! It was like magic. *lol* I've been an IE user for YEARS, but that finally convinced me to keep the switch permanent.
