Actually, that's not altogether true... you can attach a different kind of file, just change the extention, (i.e. ".car") to a supported extention type, (i.e. ".txt") and then you can attach it to a message here. Just let folks know what extention it's supposed to be and your all set.

Quote - You're only allowed to attach images in the forums.  If you want to provide a .car file or shader, you'll need to host the file on your webspace and post a link to it here or you can post the link in the Carrara free stuff area.
