Uploading Maps

[XxInsaneAsylumxX]

Well, I feel silly. I used to know how to upload maps with ease. Now, I have no clue how to. So, my question, how do I upload a map for people to download?
Also, my game always crashes when I try to export the map, can this be fixed?

Usually you put the exports, MP3's, certain custom stuff such as water and perhaps certain sky textures or ceiling textures all in a zip.
By doing this you right click, not on something, but just in an open space. Then go to New>Compressed (zip)
This makes it a .zip but I don't know how to make .rar files.
Then, upload the file to mediafire or sendspace. This should be easy and figured out quickly.
However, about the exports thing, I don't know sadly. I don't think I've even had that problem too much, but it does get a bit derpy when I export (Which I don't care about usually).
Hope this helped somewhat.~

Another question: Does it /have/ to be MediaFire or Sendspace? ;

Upload it with anything like Mediafire or Sendspace and share the link.
Just has to be a uploading site.
