There's a part of the forum on top that shows the newest posts.
It says e.g:
Newest Posts
In Count to a Thousand! by:XpHyRe
In Last Letter First! by:Paragon
In Only Questions? by:Hachen
In The band game! by:Rhi-Rhi
In The Wish Game by:CodeKitsune
Now, what's wrong is that in this case, the by is sometimes neither the thread starter nor the person that has posted last. This is very confusing. Keep in mind that in the Teal "by" the person is neither the last one who posted nor the thread starter.
Count to a thousand was made by Talyafera, Last letter First by Paragon(in this case the by is the thread starter in newest posts), Only Questions? by Countess, the band game by Rhi-Rhi (also thread starter in by in newest post), and The Wish Game by Silver Hawke.
