Subject: [alt-beam] Re: Beam genome


I think it'd work better with just the standard sub system names. A 2
motor, 4 Nv Microcore, Z-Bridge walker, or a Suneater 3/4 based Turbot
are more explanitive than the names of the creators. I can't even recal
who made what off the top of my head most of the time anyway! What we
have now seems to be working well. I liked the idea of adding the link
to the FAQ to the signature file so much that I did it! Every time I
send a mail to the list, there is a link to the BEAM TEK page! Great way
for beginners to find the link without having to ask. I think several
others have done this too. I havn't heard many newbie questions lately
(or maybe I'm ignoring them! Hehe! :)
