Hi,
I'm a newbie as well. I got a copy of Getting Started with Base from
http://www.openoffice.org. It's not easy to find. They seem to feel we need a treasure hunt for everything on that site, but...
If you persevere through \support\documentation project\documents & files, you will eventually get to a list of files. Download 'Getting Started....' It's very helpful.
Search on the site and, if you're lucky, they may send you to a place where you can download the file.
There are also other sites.
http://sheepdogguides.com is a good one but they may be only for Mac users. I don't remember.
Have fun, use a soft brick wall to bang your head against, (it doesn't hurt as much) and remember to search the forums every time you hit a snag. You'll get lots of help and many times, the answer is already here.
