[Dev] new skins, continued

[Kaitlin Duck Sherwood]

I apparently got distracted in the middle of my skins message:

"At some point, I hope to get a sessioning plug-in, which would allow 
you to choose"

should have been followed by

"which skin to use.  You'd do this by setting a variable on your wiki 
home page (e.g. Main.DuckySherwood for me).  Unfortunately, sessioning 
is trickier than it sounds at first, particularly to handle people 
behind a Network Address Translator (NAT) who all appear to have the 
same IP address.

An added benefit of sessioning is that you'd have the ability add your 
own links to the sidebar by changing another variable on your wiki home 
page.  Juergen is looking into sessioning plug-ins."
