Tim,
Always been there...
When you write your post, click on the "Preview" button and at the bottom you'll find the "Edit" function. Any mistakes can be typed over quickly.
Not to worry. Not being a real computer guy myself, I don't like to experiment with all the buttons either (I'm always afraid of making mistakes also).
Thanks for the kind compliments! We try and keep this place fun to visit. The people here are some of the nicest around! The possiblity of getting an answer or finding out about a subject is great with such a bunch of informed minds involved. Sometimes everybody is off shooting or whatever, but usually every time you visit, you learn at least a few neat things!
