For those that are not aware, a poker network is usually composed of several sites that share cash tables, sit-and-go's, and multi-table tournament schedules. For instance, America's Cardroom, Black Chip, and True each utilize the same software (sometimes called a "client") - the only difference among them is the color scheme and graphics of the software. However, all three rooms are part of the Winning Poker Network. Thus they offer the same tournaments, cash tables, and SNGs no matter which particular site, or "skin" that you access the network from.
Not all poker networks are created equally, however. Some rooms at certain networks have different cashier systems (which can mean faster or slower cashouts, different deposit and withdrawal options, etc.), and some even segregate certain cash games and tournaments among their member rooms. We have noted any site like this in the article above, no tricks here!
