Found this post on Couchmanagers.
Here is a basic run-down of the auction draft features:
*League size (up to 30 teams)
*Custom roster line-up (up to 40 roster spots)
*Mixed, AL only or NL only
*Set the budget
*Original time limit (amount of time a player is up for auction)
*Extension time limit (after there is a new bidder, what do you want the clock to be set back to)
*Set maximum number of auctions that can be going on at one time (fast drafts usually want one or two, maybe three but slow auctions usually have 20 or more; max is 75)
For FAST auctions:
*Teams nominate in order (the order is which slot the owners grabbed. So first team listed in the auction page is first to nominate, and so on.)
For SLOW auctions:
*Nominations go to either the winner of the auction that just ended, or the original team that nominated that player. You set that rule when you create the auction.
********* Most options can be adjusted during the auction. Fast auctions usually start off with maximum 1 nomination at a time, and when people have the hang of it, it gets bumped up to 2 or 3 so the draft moves along faster. Draft manager can also hand out nominations, pause the auction, edit original time limit and extension time.
Draft manager can delete a player that has been auctioned off to add them back to the auction pool and the owner is refunded.
Still in two minds, but willing to give it a go, perhaps.
Maybe we should do two leagues, one in each style!
