I am a newbie experimenting diigo since a week.

I noticed that, even if I am "signed off" from diigo, my client (FF+diigo addons) continues to open TCP connections to diigo.com domain.
Could you confirm that "signing off" means: "please stop collecting / matching my URLS, diigo!"

I read the privacy policy, and I guess there must be an easy and explicit way to disable diigo URL collection (a really "private" mode) but it is not clear to me when and how diigo client stops to send ANY information to their servers.

I think that could be very useful the possibility to define a user diigo URL whitelist, in order to allow diigo analyze URLS only from EXPLICITLY ALLOWED sites and pages.

Sorry to be a bit a alarmist... but this is a big concern to me.

thank you Graham but still disoriented:
- the "silent mode" Joel refers to is currently available?
- the current TCP connections to diigo.com are for what?
