ICQ, AIM, Yahoo at registration

[SFishy]

In VB 2.x at registration the user was given the opportunity to include their ICQ, AIM, Yahoo or MSN chat IDs. With 3.0.3 that's not the case.

I've been informed at vb.com that there's no setting to turn these to "on at registration, but not required"

If that's indeed true (and I don't doubt it cause I couldn't find the settings anywhere), how can I change it so that ICQ, AIM, Yahoo and MSN fields are included at registration time?

Thanks!
