Pay to go on the wall now, list it free and wait your turn, or stay on today's board every day.
How free listings work
Shown on your row as who built it, with a link to your profile.
$30 a month → +1 permanent point every day
On the wall as soon as payment confirms, with today's point in, and on today's board every day after. 28 to 31 points a month, by the month.
Cancel any time from your dashboard: the points keep coming to the end of the month you paid for, and every one of them stays. Why every day?
Listings are nofollow by default. You are buying attention and clicks, not link equity.
