Arch:
Here's another way. You can find your posts without filling in one form. I see you have webtv, so I am thinking that you are accessing this group through Google Groups and that you are familiar with Google.
If so, go to >YOUR< latest post, even this topic is fine.
Make sure it is your posting. In the gray with the poster's time, date, etc. in it, you will see a line entitled "show options". Right click it.
It will expand the box. In the lower right hand corner of the box, you will see "Find messages by this author". Right click it.
There 'tis.
You have another sorting option, sort by relevance or sort by date. When I clicked on "sort by date" it ran your messages back in order to about 4/12 years ago.
Your message will show up when you click on it, but you will be where your position was in the thread when you originally posted to the thread, and you will get the whole thread for referece and archival possibilities. It is block, copy, print screen, whatever after that for whatever you are after.
I believe Jack's method may go back farther in time, but I am not sure. I know it gives you the option to go back to 1981, but I know this group wasn't in existence then anyway, and I am not sure when you started posting your musings.
Let us know if you need any more help. I am sure many here are at the ready to help.
