Translation of pager in Spanish

Let's not forget how we started. We were writing each other very long messages and today we are both much more fluent in both languages. No book could have brought us that far. Cheers.
I think that working with you in this case would be just by Skype because it will be 8-20 sentences per month and always spontaneously like today's message which was 'Another five days until the weekend...'
I sent a letter 2 days ago. Did you get it? I see that you like sports. I play tennis. Maybe we can communicate together and write about sports and learn Spanish that way. Waiting for your reply.
