Talking from experience : Dont push people who dont wanna play, or isnt sure to be available, or inactive players, or are trolls to register.

If they arent registering on their own, they are more then likely to not show up at the said date / hour .

Also if you guys wanna make a last minute 6th team, dont forget that some players/egos aren't working well together (some people wont play with other people).

Id say wait last minute for a last team to join up (or more), if missing a team  just have a list of players who dont give a crap who they are playing with make 1 (not exactly the same thing as free agents).
