Hi Ben,
Twenty worksheets doesn't sound like a lot of names.
You can name sheets anything you want to make them unique.
Sorting the worksheet names makes it a lot easier to find names,
you may have to be careful if you have 3D references to multiple
worksheets i.e. sheet1:Sheet130

You could make a table of contents

If the worksheet names include dates, you would want the do be
something like yyyymmdd or yyyy_mmdd so that they sort
properly.
If you want to categorize them you add a prefix to the worksheetnames.
I had Lotus Notes which like Lotus 1-2-3 had colored tabs, I can remember
coloring the tabs and impressing someone with them, but I can't remember
what I had categorized with them. What do you use the colors to categorize.
