add me lets be friends

When did i add this guy to my friend list, cool profile though.

Yooo long time no see. I think we met playing csgo.
I have a new account now.

For "Admin System", you cannot have it used on an "Official Server" ... to make it work, see the instructions on the Workshop page for it.

There you go. And to adjust the command line parameters for L4D2:
1. Right click the game in your Steam Library
2. Select Properties
3. It will be in General (which should be selected) and will be that text box for the Launch Options .

Make sure that you have normal spaces to separate the arguments and also ones that are made up of multiple items like this example:
-nointro -novid -width 1920 -height 1080

[h1]Command line arguments[/h1]
A few potentially useful command line tweaks.
Replace any "ALL_CAPITALS" values respectively.
Reference: https://developer.valvesoftware.com/wiki/Command_Line_Options

Useful for many:
-novid -nointro
Skips the valve & intro videos without you needing to click

-nominidumps -nocrashdialog
Prevents writing to disk errors and also skips any crash dialogs

Good to know but not everyone wants:
-window
Run in windowed mode

-width WIDTH -height HEIGHT
Makes the game a specific size

-x X_POSITION -y Y_POSITION
When running in borderless windowed mode, specifies where to place the game.
