Well, I started using it, but after a few tests I decided to use the other one (Im on 3.5.3 by the way).
This is a great Mod, but the other one was easier for Multilingual purposses, and also to keep it light on the database server, since I didnt see use in using tables for it, well not until you mentioned Bcc'ing the messages, although like you say, could get private.
It would be interesting to have a Send to friend mod that could log only what products are most recommended by friends and show it on the index or in an admin view, that would be good information for Marketing purposes for sure.
