The Test-Minecraft

Hi

Anyway, I would like to ask something to all MC pros out there. Well, I don't have an account myself, and thus I play on cracked. Don't hate me for this. This particular map, which is not really completed yet, has been rather difficult to progress. And I wish, when it is done, to make it downloadable for premium users. Can anybody tell me how to upload an offline created map onto the server? BTW, I have Wifi.

Is there any way where I can enter servers through cracked?
