After creating only singleplayer-maps, I want to create my first MP-map - everything looked fine so far - but as I run my map, it seems to have the same properties like an normaal SP- map, that meaans: movement speed like in SP-mod, jumppaads and aacceleration pads don't work, and so on.
Is it necessary to create an additional .txt-file and if yes - what should it look like?

You need to play your map in the DM environment. Most likely, you are loading and testing your map in the single player gametype.

What are the steps you take to load and test?

after bsp is complete, I switch over to the game - F2 - then I pull down the console and type "map tutorials\testmp1" - why?

That's how you run a single player game and not a multi-player game. That's why you don't see the differences between gametypes.

instead, when you hit F2 and open the console, type this:

* si_pure 0
* si_map mp/[mapname]
* si_gametype dm
* net_allowcheats 1
* spawnserver

ok thanks I'll try it hope it'll work

wow was a hard work to seal the whole map but thanks it worked
