HaloMods "Classic" Read-only Archive

ok, as you can see, i am a noob.
my question is this-
what kind of mods can i use, that everyone else sees without having the mod themselves? online i created a game with the mod (i applied PFFs to the map files) and everyone else can NOT see the mod?

i have in my past joined moded maps, and i had no sort of mod, but i was able to see everything that was changed.

Omg please search this question has been asked some many times.

you can use sparkedit to rearrange stuff, then everybody will see it.
