Why not just make it so that you get 1 visit every 6 hours? That way you aren’t subject to the RNG as to when you get your visits. You get one at 12, one at 6am, one at noon, one at 6pm. or hell, switch it up a bit.

That way you’d probably have people playing all day, as opposed to all at once.

edit: you could also make it so that after pwning a forum, you get your deliveries 6 hours afterwards. that would keep people on the site all day, but not TOO much.
