Related topics in postbit ?

[misterserveur]

Hello,

I'd like to show the related topics bloc in the postbit template (just after the first post).

To do that, i tried to put the $similarthreads variable in the postbit template, but the related topics bloc didn't show up.

I think this is due to the fact that the $similarthreads variable is not declared when the postbit template is shown (i did a test with the header template, and it's not showing up neither).

Which file can i edit to make the $similarthreads variable beeing declared before the postbit template ?

Thanks.
