*If you choose to begin your reserve slot access on the first of this month, access will not be granted immediately. This is not an automated process, I need to add your Steam ID into the config files myself. It'll take zero to two days. I recommend buying reserve slots in advance.
**Steam IDs look like this: STEAM_0:1:23456789. If you have purchased a reserve slot in the past, you may leave the Steam ID field blank. Otherwise, this site's pretty good at finding it.
IMPORTANT: Once you have reserve slot access, joining a full server is very different! If the server has 22 or more players in it, open the console and type "connect 68.232.169.55:27015". (You could also bind that to a key!)
