sending trackbacks from TypePad basic

via email discussion with The Distant Librarian (who has just updated his blog with a new look) I discovered that it's possible to send trackbacks with a basic TypePad account, but for some reason, only if you use the QuickPost bookmarklet (you can set this up once you're logged into TypePad).  Also it will only show the Trackback option if the target links in your posting support that feature.  On the downside, the bookmarklet doesn't appear to support setting multiple categories.

UPDATE 2006-01-03: As part of new(er) TypePad features, you can now send TrackBacks to a list of addresses you just provide in the regular web editor (a box "Send a TrackBack to these addresses") underneath the "Accept TrackBacks" checkbox.
