The Official Babylon 5 Fan Club,
of which I am a member, has a web site too. Be forewarned, however--if
you aren't using Netscape 3.0 or higher, you won't be allowed to get
very far.
If you are interested in buying or trading B5 cards, please look at my
Babylon 5 card
page to see what I have available. Prices are available if you want to buy.
