I added a shoutbox (at the bottom of the left sidebar), so you can now leave me messages 
On the technical side, the shoutbox (wordspew) doesn’t seem to work well with WP-Cache. Thus, as a temporary workaround, I had to hack the code of WP-Cache to prevent it from caching the main page. I guess I should mail the author about that…
