Welcome Schuyler,

I was able to download the install file, but I had to change the link: 
"download" rather than "downloads".

I did read the about page first.  Thanks for the acknowledgements.

It appears that I was unable to "Load Signs".  I clicked the button and 
nothing happened.  I waited several minutes.  After, I played around 
with the buttons on the Load Data page, but nothing seemed to do 
anything.  I have Android 2.2.2.
