Gamerforums brought this to my attention
here and I have done some tests to catch the bug:
If you attach a .txt file to a post, the board does not parse its content so your special tags like
Code:
https://vborg.vbsupport.ru/vbimages
are kept. But if you choose to edit it here via "Edit" link, tags and variables are parsed and changes. Maybe it would be nice to correct it since parsing in text attachments is not something desired..Just FYI..
