I've just installed Drain Hole and think it is a fantastic plugin!! Everything worked as described until I went to examine my RSS Feed by Feedburner. Oppss! Not working.
Since Drain Hole uses pathnames relative to the site root it was no surprise actually that the RSS Feed would generate errors for the subscriber.
Any chance of getting an update that will fix this? It should be relative easy to embed the site root as part of the download path name - the way it is being done if you download from the WEB site itself.
