I am on a dial-up system but I listened to about 17 minutes of the podcast and enjoyed it ! It would take a couple minutes to load about 5 minutes of talk then do it again with each 5 minute section.
I have Christmas cactus blooming now so your mention of it will get me to check out that forum. I have also grown a couple of Poinsettia's for about 3 years and they did color back up for me so now I need to check that forum as well !
