Or you can just basically do like mine. Here are my banners for example:
set g_bannertime 120 //Server banner strings to display
set g_bannerlocation 2// (default 2) default location for banner printing (0 - server message area, 1 - player chat area, 2 - center of screen)
set g_banner1 "^2Welcome to Prospector's^5 Place."
set g_banner2 "Visit the website at
http://bani.anime.net/banimod"
set g_banner3 "^1This is a Wolf MP game. Enjoy everyone.
Notice that my g_bannerlocation command is set to 2, which displays the message in the middle screen. For the chat area, you can just set it to g_bannerlocation 1
You can set as many banners as you like. But, don't set the g_bannertime to 30, because it is considered message spamming in front of the players. 120 should be fine as well. I took this idea from the =SWAT= clan forum. I've recently found some beneficial commands for banners.
