Custom mod name??

[Rensa]

We have a server on our demo, where the place where (tdm,conquest etc...) is supposed to be, but it shows a custom name, like:Mushroom Mod, or clan mod.
Anyone know how its achieved?

NOTE!: Also how do i stop glitching. I know i need to use the fence etc... but if i place it in static files AND give it its location it does no damage if i go into the glitch area..

I think all they did was change the map name via the lexicon file.
