I really don't care whats going on in SL or at LLs while I'm not signed in. How can I stop the e-mail spam. I don't want to hear about events, the super cool stuff people are doing, the greatest new thing, the ways I can make things better, ways others make it better. I want it all to stop I would like to keep my account but only hear about it when I'm willing to log in.
