Okay, I've been trying to do this for a couple of months (!) now, actually. Everytime I subscribe to some Email Lists, Logos will first save the selection. But after logging out and in again, the selection has gone to some kind of default - just not the selection I have made. In other words: I can't get Logos.com to save my selection of Email Lists.
And one more thing that seems to be a bug: When selecting "Unsubscribe", the description states "We hate to see you go, but if you want to stop receiving promotional emails, check this option and press update." Thing is - there is no "Update"-button.
Any help? Thanks.
