I substantially agree.

Now i feel myself in a relational maze. But from now, Gabriele has a week of
time to give us a complete bug-free program. Count down has started :-)
About all the rebol db programs, i wait a comparative review from you (another

Can't you say us the link to find the db which are not on rebol library?
