What server technology are you using. If you're on a MAC I
can only assume you're using Unix server. If this is the case, you
can't use ASP.NET or ASP with these servers. They're Windows
technologies. I know ASPNET C# hasn't been designed to run on Unix,
yet. I think someone is working on it, not sure when available
though.
Unix server would be Apache / Free BSD / Red Hat, etc.
Unless you're using a Windows Server you can use C# or other
ASPNET languages (VB.NET)
You now have a choice. Either to switch to Windows and use
Windows technology, something that could prove costly.
Switch from ASP.NET technology and use either ColdFusion or
PHP.
I recommend ColdFusion simply because it's easier to learn
especially if you have no programming background and it's more
scalable for growing projects.
You can download the developer edition of ColdFusion from the
Adobe site. This is free and will remain free.
You can then use Dreamweaver and ColdFusion to develop your
site
You can also download PHP from PHP.org site and
You'll also need to get a database for the site. Since you're
on MAC, I would recommend MySQL it works with both ColdFusion and
PHP
Dreamweaver will work with either ColdFusion / PHP, but it
like CF better
check with you hosting company to see what technology they
support and what cost. I use www.hostingfest.com as they support
ColdFusion / ASP / ASPNET 2.0 at no extra cost
