Hi!
Since I've sent out my first letter in 2006 (14 August 2006, to be exact), I've started to keep records and I'm still using the same notebook.

In the book, I write the following:
- Name of person
- What I sent (letter, SASE, IRC, photo, etc.) and to which address
- Date sent
- Date received
- How much the postage to send it were (quite interesting, it seems the postage in South Africa for a small envelope went up quite a lot!)
Since I started using Fanmail.biz and sent out mail the "correct way" (SASE, SAE or IRC, etc.), I've never had a RTS.
Thanks!
