Bruised, Bothered and Bewildered---but otherwise in the game

I guess from all this rebuild of our site, the one lesson I have learned is---make a copy first, then try changing it-----I have now spent the better part of three hours trying to replicate my list of my blogger friends---and the only way I know how to do that is to go back and review comments on earlier posts, click on their icons, which takes me to the profiles, which in turn reference their blogs, which I can then go to , copy the URLs, and re insert them in a new blog roll . The work goes slowly-----I have lost all my buttons, so who knows what is happening with my technorati, sitemeter, bloggertalk, and google accounts??
How did this all happen you ask?---the long story , short version is---I wanted to learn how to do some HTML code changing. add a Technorati widget to my site----Not knowing just what I was doing, I created a dummy blog with which to experiment, and learn how, then with my learned knowledge apply it here to this blog----well I got to working with this blog, the new dummy blog, the technorati page, and was flipping around between them all, and decided it wasn't working so would just delete it all---which I did---unfortunately happened to be in THIS blogs HTML at the time, thinking I was in the dummy blog----so you can classify it as just a stupid error---an accident that shouldn't have happened----anyway it will be days before I can get Humpty Dumpty back to some resemblence of its former self-----
