Hello - If you can read this posting, this means the earth is still intact. By chance the earth was broken into fiery particules by meteors causing colossal catastrophes. OK, maybe I'm lying a little, but that doesn't mean that you can't write emails now and have them send in the future. Using site timemachiner.com, I've written an email to be delivered in 2030. Hopefully email, and I will still exist. I wrote an email to remind me to have my bag changed.
Try not to break the future!!
