Of course, that doesn't explain why those links disappeared after about 20 minutes, and right offhand, no other explanation comes to mind. They weren't my usual entry nodes, no. It's a mystery.

Please write your Mail to [EMAIL PROTECTED] with mailbody including: unsubscribe or-talk btw: When finally will list-subscribers check their mailheaders for this? It would never have occurred to me to check the headers either, so perhaps you are being too hard on them. Possibly I was too hard on this, but this unsubscribe-question comes so often on all mailinglists, that it bothers a lot nowadays... and it's been answered frequently already - so often... Some people are just too lazy to look into how to unsubscribe from a mailing list properly. I'm sure a 30 second google would have been sufficient, but they'd rather email everyone on a mailing list asking that information instead as it involves engaging less brain cells. -- Erilenz

That's just common sense.

That way they would still have to take some responsibility for getting what they want, but could no longer harass my list. Scott Bennett, Comm.

Tor makes its directory fetches using one-hop circuits. It started doing this in 0.2.0.22-rc: - Enable encrypted directory connections by default for non-relays, so censor tools that block Tor directory connections based on their plaintext patterns will no longer work. This means Tor works in certain censored countries by default again. Vidalia shows all the circuits, because it can't really distinguish what you (or your Tor) are planning to use the circuit for. Down the road, we may switch it so it makes these one-hop circuits to your entry guards. No point revealing your existence to any more relays than you have to. The phrase for this new design would be directory guards; you can see it scattered about the TODO file and roadmaps. --Roger

I went straight from 0.2.0.19 to 0.2.0.31 when I downloaded the latest Tor-Privoxy-Vidalia bundle, so if there was anything in the 0.2.0.22 release notes I missed it. I don't think I've ever seen the roadmap. GD

You can find two of them in https://svn.torproject.org/svn/tor/trunk/doc/design-paper/ Alas, they're not exactly well fleshed out. I've been working on a newer version that captures more of what we've been up to lately and what we hope to be up to in the next several years. Stay tuned. As for the TODO list, take a look at https://svn.torproject.org/svn/tor/trunk/doc/TODO.021 and https://svn.torproject.org/svn/tor/trunk/doc/TODO.future --Roger
