This is my vimrc. I want to fix it so that it doesn't show >---- >---- when other people tab. Thank.

Remove these lines:

set listchars=tab:>-,trail:~
set listchars=tab:>-

set list

is doing this. You can

:set nolist

if it is bothering you but I recommend keeping it for python files (you might be coding in python looking at that autocommand). ie. ... Learn to love it. create a mapping if it is a regular issue.

Also there is

:retab

to remove tabs if you have an expandtab setting.
