marshal?

hi everyone!!!
i just got some freetime to do this tutorial (haha im a newb xD)
so in this tut i show you how you can simply show ur friends ur marshall xD
ok
first what you need:
1:something to open up pictures (paintnet or so just google it =P)
2:you must know your rank
3:your crossfire folder
4:2-3 minutes.

ok lets get started
1. first open your crossfire folder (computer ->for example C:/ -> Subagames/Z8games -> crossfire)
2. now open up the folder UI (fourth folder)
3pen the folder class (first folder in UI)
now you will see BigClass_1 to BigClass_100
4. look up your rank (for example trainee 1 (it has the codename BigClass_1)
5. now look up the rank you want to be (like marshal its BigClass_100)
6.ok now change the name of BigClass_100 to "BigClass_1000" for example
7.change the BigClass_1 to BigClass_100
8. change your BigClass_1000 to "BigClass_1"
ok now repeat 5-8 with class_1 and class_100
now when you login your crossfire and open your soldier profile
and you will see that u are marshal

now thats it
