Maps not saving as a Pk3

[Drac3997]

I have an issue, my maps arnet saving as an pk3, i am saving them as exactly this
map-TheRig-alpha-1.0.0.pk3
but it comes out as
map-TheRig-alpha-1.0.0.map
I have a feeling that I am supposed to save it a different way or something
and also I cant upload the maps from the Base folder(the default maps)is there a reason for that?

and I am saving my map in Tremulous/Base with the other default maps, is that a problem

I also havent added the textures yet

You need to compile your map first, then you have to make a proper pk3 file (it's juz renamed zip archive), or just /devmap it from tremulous if you want to test it. Everything is described at the mapping wiki:
