SignPuddle 1.5 updates

[Steve Slevinski]

Hi List,

I've made a few updates to SignPuddle 1.5. 

There should no longer be a problem with cross posting between puddles.  
Which ever puddle you write a sign or document in is where the sign or 
document will go.

I've also cleaned up the multiple user problem.  You only need one user 
account and you can user any login button.

If you encounter any problems, please let me know.

Regards,
-Steve
