Popular Reviews of The Karen & Ellen Letters

I've had the letters since 1997 & they provided so many hilarious moments at holidays. We never thought they they were real. Many questions were answered by the podcast and I found my set isn't complete so much appreciated. I feel let down though that there wasn't one final wrap up episode. Josh said he stupidly or cruelly published Karen's emails but why? Was there backlash? What about Ellen? Which parts did Mark fabricate? I also noticed the inconsistent handwriting. Was Mark supplementing? Thanks.
