This is a technique that Mark Forster has used and I read about a year or two ago. It is not something I'd tried until recently but seems to work well. I could go into a lot of detail and explain it however this has already been done for me here. In fact I actually used it to start blogging again ... after a break of a year. My technique was "I'm not going to write lots on the blog, I am just going to check I can still login". This seems to have broken the ice and a lot of posts followed.
