That's no biggie !! Just set a date -- start/stop times -- entry fee/big fish fee -- find a digital scale -- appoint a weighmaster & money holder -- decide on rules (or use the ones we used for this year's FJT's) -- set a minimum limit on number of boats to commit to showing up -- make sure your tourneys aren't in conflict with other series tourneys, opening hunting season dates, holidays, or other functions that might lower the number of participants -- post all the info here -- then go for it.
You might also want to mention it on the state forums of neighboring states, and even in the Crappie Tournaments Forum. You'd want to give possible participants at least a month notice, in advance of the chosen date, in order for them to have time to make plans to attend.
You can make them "anything legal goes" (any method/number of poles) or "specific/custom" (one pole only/no live bait/specific method only) ... choice is yours, to make it as easy or hard as you want it to be.
