i cant understand it fully ,but i have downloaded cricsim .what i do now.please tell me in short
If you're participating in someone's league as a team manager, all you have to do is pick squads as per the league's rules, post lineups on time and comment on your team's performance in a constructive manner. If the squad is already picked for you, just do the last two.
If you've signed up in someone's league as a player, all you have to do is be active and post constructively. Only if you're selected as captain will you have to post squads and lineups.
And if you've downloaded cricisim and are looking to start a league of your own - don't, just yet. You are still new and it'd be better if you first participate in a few leagues and get to know what they are about or how they are run before you go off starting your own. Participating in leagues and getting to know the members will also help you get more signups if/when you start a league of your own.
