You've probably noticed the little bookmarking icons for submitting a conversation in the forum to various places.
See the icons below starting with the little man and hover your mouse over each one, there is Digg, Technorati, Spurl, Del.icio.us, etc.
They are a convenient way of keeping track of post you would like to bookmark and refer to later.
I recently started using the last one - Mister-Wong.com and like it a lot! I think it will replace my Del.icio.us collection of bookmarks.
The English version is currently in beta, but I was able to get an "invite" within a day (the password I received was "wong13", you might try that first!)
