Well, that was a first try to produce a new index. There are some mess-ups, but I don't know what caused them yet.

Sometimes an odd character in the title can mess up the output as the data travels through Sql to an export from Cpanel which goes to Excel as a CVS file with a final save from Excel as a tab-delimited Txt file of about 1200 lines. Then I copy/paste the 1200 lines into this Index post.
