in the code, there is a do_action('ipmort_done', 'blogger') line.
It could be great if you would add a do_action('import_start') action too, when the import starting.
It would be useful, because I'm caching the whole site, and because of that i should purge the blog pages when a new post is created (in this case imported).
And if I would know when the import started, then I could manage, that purge the cached pages only when the import is done.
In the wordpress importer, there are these two actions.
