what is a threadbit and a forumbit

[dynamot]

Can you guys lend your insight into interpreting what this means.

If you look at this link:
https://vborg.vbsupport.ru/showthrea...t=125654#posts

Can you tell me what is the name of the file he is referring to?

" threadbit template updates
(1) On the very first line, change "

forumhome_forumbit_level1_post updates
On the second line, change


forumhome_forumbit_level2_post
On the very first line, change


pm_messagelistbit
On the very first line, change


memberlist_resultsbit
change

Initially I thought (1) was forumdisplay.php. But forumdisplay.php does not have any "<tr>" in it

Tx in advance
