I came to this site to post the things I made so I won't lose them
I'm still keeping this TUS Account, cause I don't want to lose everything I made for Certain worm games like Armageddon.
If don't have enough disk space on your computer to download all your assets you've made so far, you can use cloud storage like Dropbox.
If you're afraid that you'll lose all your assets on this site if you don't keep logging in, that won't happen because it doesn't depend on whether you here or not, unless TUS server goes down.
If you want your assets to be accessible by other wormers, they're going to enjoy your work throughout all TUS lifespan anyway.
If you somehow feel guilty for not doing more speechbanks or feeling responsible for maintaining your assets on TUS, that's totally up to you, you're not obligated by anything here.
