Inserting block on forum board

[Sono]

I would like to insert a custom block into the forum board, one in the middle of the topic list, and one under the topic list. I attached two images indicating these places with a red line. Where can I find the corresponding code in the forum files to add a <div> block to the code?

An ad mod will likely pull that off for you.

I have some mods like that but the problem is that most of them does not want to install into the mobile theme, and the mobile theme lacks many corresponding elements that the mod is looking for.

However I managed to solve the issue. I realized it can be done with inserting the block HTML code into the desired .php file with the command:

echo '....HTML... ';

Where to place the file can be investigated by trial end error. I tried various locations in the files, and in the end I found the proper places.
