Re: [9fans] lsub.org

That´s it. lsub.org is gone.
I think our dns is out of procs, and nobody is in town. I don´t know
if I´ll have
to go back to madrid, or just wait until next Sat, when I had the plan
to return.

Thanks a lot for the script, that´ll be the first thing I´ll install
upon return.
(btw, nemo.mbox@gmail.com is still a way to reach me, should anyone have to).
