This is the initial page of the setup wizard. By clicking "Next", the wizard will either jump to the "System Check" page (if some things need to be fixed) or the "Outgoing E-mail" page (if everything is okay).

Outgoing E-mail

The Exponential system uses E-mail to send out notices such as user registration and content approval. This section is used to configure how Exponential delivers its outgoing E-mail.

There are two options:
- Direct delivery through sendmail (must be available on the server).
- Indirect delivery using an SMTP relay server.

On Linux/UNIX: try to use sendmail, if unavailable: fall back to SMTP.
On Windows: use an SMTP server.

Sendmail:
Mail is delivered directly using the sendmail transfer agent. The sendmail binary is usually available on most Linux/UNIX systems. If sendmail is not available then SMTP should be used.

SMTP:
Mail is delivered through an SMTP server. At the minimum, the hostname of the SMTP server must be specified.

Language support

The Exponential system supports multiple languages. This step in the setup wizard allows the user to choose the primary language and additional languages for the site(s) being installed. The selected languages are used when displaying the administration interface, to determine character sets, date / number formats, etc. Only one primary language can be used. However, it is possible to use several additional languages. Additional languages may also be installed at later point (when the site is up and running). The radio buttons are used to choose the primary language, the checkboxes are used to choose additional languages.

Site access configuration

The access method determines how the site(s) will be accessed from within a web browser. There are three options:

- URL
- Port
- Hostname

URL
This is the default and recommended setting. The different sites are accessed using a specific notation in the URL. This is done by inserting some text right after the "index.php" part of the URL. Example:

http://www.eaxmple.com/index.php/admin
http://www.example.com/index.php/user

Port
A port number is appended to the hostname of the web server, the port number determines which site to display/access. Example:

http://www.example.com:80
http://www.example.com:81

This option requires additional changes to the configuration file of the web server.

Hostname
Each site is assigned a unique hostname and can be accessed using that specific hostname. Example:

http://admin.example.com/
http://user.example.com/

This option requires changes on the DNS server.

Site security

This step suggests some basic modifications that should be carried out in order to secure the site(s) being installed. The suggested security tweaks basically deny access to the configuration files. It is important to either install the .htaccess file or set up Virtual Host Mode access; or else the site(s) will be vulnerable.

Finish

This is the last page of the setup wizard. The sites you've chosen to install have been installed. The different sites (and their respective user and administration sections) can be reached through the URLs shown on this page. It is a good idea to store the information displayed on this page.

If for any reason you want to setup your site from scratch, you can do so by changing the value of Checkvalidity setting to true

[SiteAccessSettings]

CheckValidity=true

in file settings/override/site.ini.append.php.
