the cougars posting is so bad i cant even read this
He's talking about kugutsumen.com, an Eve meta-gaming/trolling forum.
What is/are "fraps"?
video capture software
And why would one player need to run more than one Eve client?
Many, if not most, Eve players multibox more than one account at a time (the average number of accounts/person is probably ~2). Especially people who own supercarriers (such as the focus of the article), as those ships can never dock, thus one for all intents and purposes needs another character to fly other ships.
Other common uses for multiple accounts are dedicated support characters (haulers, boosters, healers, etc.) and mining fleets (some people will run dozens at once, crazy I know).
