A crude way but simple way to index an RSS page. You can also embed the sheet on your own pubwriter page.
URL of RSS Feed
Title of RSS feed (optional)
=ImportFeed(A1, "items title", FALSE, 10)
=ImportFeed(A1, "items url", FALSE, 10)
=HyperLink(B2, A2)
After I create the sheet, I hide columns A & B.
You can access the google sheet here.
