A very handy tip that someone told me about recently is how to send an email from a computer as a text message on a cell phone. I have this feature on yahoo, but I didn't know the email addresses below existed to do it with virtually any phone company! And then I REALLY didn't think it would work from Dan's ship. But, lo and behold, we tried it out, and he can text me from his computer!
When you work on a 8-10 hour time difference, this is a great asset! I get to have that wonderful feeling of a surprise text from the one I love! We combine this with K7 (Day 1's tool). Dan can text me for free, and then I K7 him back with an answer or "I love you, too". I can't text back because it's an international texting fee, but I can K7 back for free! This is the closest thing we get to IM (well, and emailing at the same time). You may want to use it, too:
