So now I'm trying to change wakaba's setting so that everytime anon post something, he will be redirected to that same thread he posted on. The way user had to go back to front page after every post is annoying to me.
I found the following supposedly related line in wakaba.pl:
# forward back to the main page
make_http_forward(HTML_SELF,ALTERNATE_REDIRECT);
I have zero knowledge with Perl so I hope someone will help me here.
