How are KizzaRules and Katalonian? I haven't got a chance to play with them yet. They have weird Steam profiles, with very few games and even a VAC ban.
If there are any problems, I'd like to know about them as soon as possible so I can address them. I am sceptical about adding too many new people before Saturday, and then having that session become a clusterfuck because of it. But if I can get word that the new peeps are cool, I can keep adding more of them with more confidence.
