While not true in this case that you sent - static lists fall into disrepair 
frequently.  A couple of months back we tried this in the APAN region and 
found about 1/5 still worked well after being posted to an 'official' wiki.  

It doesn't hurt to ask those on the front lines that are adopting pS for some 
insider info - that request applies to all, even if they ate not in South 
Africa.

Thanks;
