Got a great question from an OPML Editor user today 

This person had a tab-indented text file that he'd opened in the OPML Editor. It opened perfectly, with his outline layout preserved. However, when he saved the outline, it was saved as a plain text file, not OPML. How do you change that?

Screen shots should illustrate:

Right-click in the title bar on the file name:

Select, "windowTypes," expand the table that pops up, and change the value for "flOutlineDocument" from "false" to "true."

Ctrl-S to save the metadata, then close the table and save the file. Voila! Now it's OPML! Look at the file in Notepad if you don't believe me.

David Wilkinson wants to set up a public OPML Community Server and is looking for feedback and suggestions. 

Wilk: It's really nice to see that you care, but Optimal is not what's been keeping me so busy. Sadly, the changes to Optimal I rolled out yesterday were only about half-complete (although all the features I had planeed were there) and had been sitting in my testing version for weeks. "Real life" -- i.e., my day job -- has kept me very busy leading up to a big deadline on 3/31.
