Just noticed a few new things at YAFU ...
The url is now
http://yafu.myfirewall.org/yafu/There is a new application called "YAFU for small composites" (composites below 110 digits go to this app)
One of it's goals is now
"to factorize numbers of 70-130 digit length which are needed to bring Aliquot Sequences to a size of 130"
