When inviting other teams, don't invite teams with a huge payroll if you don't want those teams. And before you accept an invitation, ask the inviting manager if there is a limit to the roster payroll for the teams getting invited. And if there is no limit, check out the other teams joining the league before accepting the invitation, and then keep checking to see what other teams join before the league is activated. And if you just don't know who's going to be in the league and/or won't be doing the research on the league, then just create your own darn league and invite who you want.
That works for me.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
