A little recap of what I have done ... and then my questions Q1, Q2 and Q3

1 - I developed a RoR app that I deployed on Heroku.

biowatts.heroku.com

2 - I bought a domain name at GoDaddy:

biowattsonline.com

3 - I am using Zerigo addon as for the DNS

heroku addons:add custom_domains
heroku addons:add zerigo_dns:basic

4 - Added my domains in Heroku

heroku domains:add biowattsonline.com
heroku domains:add www.biowattsonline.com

and subdomains

heroku domains:add calculator.biowattsonline.com

Q1: Where do we configure the forward to http://biowattsonline.com/biogas_calculator ?

5 - Configured GoDaddy adding the Zerigo domains

In the Nameservers section

a.ns.zerigo.net
b.ns.zerigo.net
c.ns.zerigo.net
d.ns.zerigo.net
e.ns.zerigo.net

The GoDaddy DNS section is empty: "Not hosted here"

Ok this works all fine ... http://biowattsonline.com is correctly found

6 - Subdomain forward

I want calculator.biowattsonline.com to be forwarded to biowattsonline.com/biogas_calculator
Q2: So I created the forward in GoDaddy ... but is that correct?

7 - GoDaddy email

Q3: I have one free email account with go GoDaddy, only now that I am using Zerigo I don't know how configure GoDaddy to make it work again?... because it work with the default values

Any ideason Q1, Q2 and Q3?

Thanks,

Joel
