Hello, Master, and welcome to the forum. The blogs on the forum that are provided with your account is an excellent way to keep a diary. Otherwise, if you would like to play along in the discussion forums, we all will look forward to seeing you there.

Welcome to Philforum.
Theaetetus makes an excellent point about the use of the blog feature here resembling a diary, although you can expect comments along the way. For the most part, the forums themselves are for the presentation and discussion of philosophical positions and viewpoints; you may wish to share some of your own views as the dialogues suggest them to you.
Cheers,
John
