When I first started playing CC it was still played by post, with moves (and scoresheets) going by mail. I took a break from it for a while, and only got back into it when the internet had really taken off.
Even then my return tournaments were played by mail, but in this case, email. Server based chess was only just starting to become popular (and technically feasible) so my early events involved remembering to send moves. There were some issues with this system (lost emails, stuff going into the wrong folders etc), and it wasn't until server based chess came along that they were resolved.
I did take part in the first Australian Email Championship and I think I finished mid field. There were a few long games, but also a couple of quick ones, like the following. My opponent captured on h2 and offered a draw (which was unavoidable anyway) but the line after Kh1 is slightly more interesting.
