Hi!  I am Jezz, and a newbie here.
This is the first time I have visited Second Life.  Got in successfully around 4:00 PM PST, did a little avatar customization and walked over to the shore near where I entered.  Then experienced what seemed to be lag.  Ben told me that the area I was standing in was notorious for this.  I tried to Fly to a couple of places by selecting first "Track Ben" and "Fly" when prompted.  Then tried clicking on a landmark (I believe) and neither worked, so I quit out at about 4:55 PM PST.
When I tried to get back in, it seems I am stuck at the "registering agent" phase and the progress bar is stuck half-way and pulsing.
Perhaps a server is down?
Thanks,
Jezz
