I like to upload an small addon to curse, however i'm new and therefore i have some questions:
1: "License:", "Custom license name:" and "Custom license text:"
What License do i need to choice, its just a small addon, free to change for own use, not to update for others then me and may not be redistribute, unless they ask premission to me.
So, what choice is the best option ?
2: Where can i find the "upload file" (or is that after creation?) and what file extention must that be, plain as is, *.zip *.rar?
1. All rights reserved is the simplest option for what you described, you don't need to choose a custom license, you can change it later in any case.
2. Project needs to be created first before uploading files, .zip is the accepted format.
Pick curseforge if you don't want to bother with source control and prefer the simpler method of uploading the pre-packaged addon.
