The InviteSignup extensions allows account creation to be offered to a user on a closed wiki where it's restricted.

The extension adds a Special:InviteSignup special page, available to users with invitesignup permission.

The inviter, from this page, by entering just an e-mail address, can quickly invite a single person to create an account on the wiki.
The person can then set a username and password, confirming the creation of the account, which is logged; until then, no account is created.
The inviter can optionally set additional user groups to which the account will be added automatically after creation.

Extract the snapshot and place it in the extensions/InviteSignup/ directory of your MediaWiki installation.

If you are familiar with Git and have shell access to your server, you can also obtain the extension as follows:

Download and move the extracted InviteSignup folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:
```
cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/InviteSignup
```
Add the following code at the bottom of your LocalSettings.php file:
```
require_once "$IP/extensions/InviteSignup/InviteSignup.php";
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

You will also have to create a new variable $wgISGroups containing an array of groups where the user can be setup: $wgISGroups = array( 'user' );
