HaloMods "Classic" Read-only Archive

I am new to modding so I have several questions that Im sure many people will be able to answer easily, first off I have been able to mod Halo PC but I dont understand exactly how some of it works, I download the ppf patch for maps and I have ppf o matic, I know how to actualy make it work but when I do it, it doesnt matter because anyone els who gets on my server cant see anything I mod, just the extra guns that were added and unlimited ammo and things like that, so from what I understand after messing with modding is that the other persons on my server have to have actualy modded there map with the same mod i have to see it, right? also I want to know how to do things myself like adding guns all around the map, and adding the secret little teleporter (I guess its a teleporter) to teleport yourself to the top of bloodgulch or wherever you want, also half the mods I download off of here (and they are stated to work with Halo PC) will not work when I try to get on my server, the game will shut down and an Exception! window will pop up and the hard drive will read like crazy and the send/dont send windows XP window will pop up, WHATS UP WITH THAT?? and I want to stress that I have standard Halo PC retail game not CE or any other versions that may be out there. Hopefully someone out there has some answers for me.

with the exceptions. make sure you are applying the PPF patches to an UNMODDED .map file.

If you want some specific answers, you can PM me individual ones, or post here again with numbers like

1) blah blah blah
2) yadda yadda ya
3) indeed
4) help me damnit!
5) etc

you know what i mean

Yes I always backup the map so when I want to try another mod I can just copy over the modded one and start fresh, anyway here are my questions.

1)how do i add guns all over the map and add the teleporters (like i said before i guess there teleporters) were you run into the wall or jump on a rock or whatnot and it teleprts you to like the top of bloodgultch or wherever els you want

2)does the client computer have to actualy have the modded map file also? because when i mod my map people who get on my server cannot see anything changed, like one i got off of here had a wood base type thing in the back of bloodgultch with grenades in the window, the people who get on my server see nothing but grenades hovering in the air, no wood base thing.

and 3)what is up with the Exception! window that pops up half the time i do a mod to a map, halo shuts down that window pops up with a send/dont send error report window.
