Just by email, you may say 'Ooh, I find you!'. Well, joking apart,
I mean if you have something unrelated to any post on this blog or stuff should be in private,
you may mail it to .
However, you might need to wait a very long time to get my reply when I'm terribly busy.
Or you may leave a message to the Cbox other than by email.
Sure, it is recommend that you post it as a comment to posts on this blog.  :-)
