Here you can get the File Upload manager. You can upload new files up to 250 MB. If the file is larger than that you have to split them into smaller parts. Copy the link to your file and post it in a new thread here. Name your thread to your new modification. Once your new thread is activated others can download your file(s). A short description, the content of your ReadMe file and Screenshots (max 256KB and max 640x480 and max 3 are allowed) of your mod are desirable. Make sure you give credit where credit belongs...
