hello world. first: my english is not the best, i hope u fully understand my question here

i have a lanparty site. i want to write a new slogan for this site. (lanparty = we make partys with computers for gaming in a lan [local area network])

(WAN = Wide Area Network(means for playing or do things over internet | LAN = Local Area Network)
