Thanks to Andrew for all the good information about tags. He helped me find a mistake I was making in Technorati that completely knocked me out of their system (at least I think that's what did it, anyway it's fixed now).
I wanted to share an idea I had that is working well. Now mind you, I'm in first grade in this s'cool, so if everyone else already is doing this, just indulge me. I am pretty proud that I thought of it.
On Blogger there is a place in dashboard (under Settings / Formatting) where you can create a post template by adding any html language for formatting that you want to use on every post. I use the same tags for Technorati about 90% of the time, so I made a template with the tags on it. That way they automatically are on the new page when I create a new post. It's great. It's much easier than saving them as a text file and cutting and pasting every time, which is what I had been doing. And if I want to change one of the tags, I can just go into html when I create the post and change what needs to be changed.
I hope there is someone reading this who is as technologically challenged as I am who can benefit from this idea.
