You can indeed use a home network to connect through a normal modem.. if fact as long as the computer with the phone-line is online anyone on the network can get on.

Do I recomend this? No, I remember it being a pain to work for some odd reason, that and I know some sites don't like it... so if both the comps were on the same site.. heh it could led to ban.

We were doing this with 4 computers and one dialup connection.. only needed one modem as well.

Actualy you know what... I can't remember how exactly we did manage it that had to be what? 5-6 years ago? I woud have been as young as twelve.. my memory doesn't work THAT well.
