E-mail address - Can we change them?

I'm gonna make an email address for each of the following things:

eddy102293@maddenholics.com
reypoints@maddenholics.com
support@maddenholics.com

and maybe a few more...

Here are my questions:

What level of members can see webmail.maddenholics.com?
Can I delete an email address?

there is no level for this..you have to give the address of the webmail to the users whom u have given the mail ids to.

Yes you can delete the email address

Thanks.

How long until my domain name is up and running? I've been waiting for a couple of days now.

How come I haven't got my domain name yet?

It takes around 4 to 5 working days to process your request(Atleast was for my case). If it has been more than that, try PM'ing Typlo with a receipt of your payment.
