About...

  A little bit of kudos for all of the very hard working guys/gals who made it all possible

## Options

The `Options` box in the upper left hand corner controls the level of detail and customization offered on the tabs to its right. Below the Options box is a brief description of the level chosen, and what can be done in that level. The levels are explained below.

`Basic`

  This exposes the `Login appearance`, `Login behaviour`, and `Face browser` tabs to the right of the `Options` box.

`Expert`

  This exposes the `Security`, `XDMCP`, and `X-server setup` tabs to the right of the `Options` box.

`System`

  This exposes the `Paths`, `Environment`, and `Chooser` tabs to the right of the `Options` box.

| Expert option and security
| Enabling the expert option, allows for changes in GDM's security to be made. Improper configuration may lead to vulnerabilities for attackers.

| System option and system health
| Enabling the system option, allows for very specific changes which can impact the operation of your system. This option is only recommended for those who know exactly what they are doing.
