How do I find my comments?

The Manage Comments page gives you a list of the last comments you posted on the site, and the last comments you received on your journal. The number of comments that will appear in the list depends on your account level; free users see the last 10 comments, paid users the last 100, and premium paid users up to 150. You can reach the Manage Comments page from any main site page by choosing the Recent Comments item from the Read menu when you are logged in.

Dreamwidth does not provide a way to search for all the comments you have ever made, and you can not search for anyone else's comments. This restriction is for privacy as well as site performance reasons.
