I'm not sure how well suited they are to Realcent's needs as far as the technical
requirements of running a message board but the DNS provider I use also does
hosting now as well:
http://www.easyweb.comI don't use them for hosting because for a variety of reasons I like running my own
server box on my own premesis. However they've been incredibly reliable for DNS
and E-mail for the aproximately 14 years I've been using them.
They might be worth a look.
