Dan Kuykendall, The creator of Podpress graciously integrated support for the Blubrry Statistics redirect in Podpress. The support makes it easy for Blubrry members to implement the redirect in Podpress.
There is a syntactical error in the Podpress code which prevents the Blubrry redirect from working within Podpress. The code fix have been sent to Dan and will hopefully be included in the next version of Podpress. In the mean time, Instructions how to patch Podpress version 8.6 are available on the RawVoice support site.
