Sourceforge seems to be working fine for me; I've checked in your 
changes along with a few of my own. Mainly, I've tacked on a few things 
to the Boost.Signals summary where we've matched features with 
libsigc++2 (e.g., we've always been able to do signal-to-signal 
connections, and users requested slot blocking/unblocking which is now 
part of Boost.Signals).

I'll make some time later today to crunch through some draft-quality 
proposed wording (mainly based on the Signals docs and my superficial 
understanding of libsigc++2); that will probably show some design 
decisions I'm assuming we've made but we actually haven't :)

For instance, reading into the libsigc++2 section a bit, it looks like 
building a slot is very explicit. In Signals it's completely implicit: 
you only see slot<> types if you need to pass a function object through 
a non-templated function.
