Here’s a lil secret 
hehe
I ‘require’ 4 posts during the week of the tournament to recieve the password, and I get a buncha activity whenever I have a tournament as a result…
However, I don’t count the freakin posts 
Who has time for that! lol.. Many people just follow the rule, those that don’t I’m sure they realize they don’t ‘really’ have to ..
Also.. I never email the password, I email a link to the post or page where the password can be found, there you will also find step by step directions as to how to register..
First click the banner.. then sign up.. then go to multi tourney tab.. then etc etc etc .. with a note telling users that already have an acct to skip steps 1 and 2..
This always brings them wherever I want them to be.. and never to the same place twice, so they actually do have to at the very least visit the site to get a password
