I don't see anyone else suggest this so here we go.

Right now in vrchat when you upload a world or avatar only the account that created that blueprint id can upload to that id. It would be nice to have a system where the blueprint id creator can allow other accounts to upload to that blueprint id.

It would help groups that have dev teams that manage a world. It would eliminate people having to bug the blueprint id owner to upload the world. Or having a vrc account that they all use.

It would also help people that commission someone else to work on their avatar. Instead of them having to download a unity project and upload it themselves they could just have the person they are commissioning upload to the blueprint id.

It would also improve account security since instead of sharing your password with someone else you just put their name into the sdk/website and now they have access to that blueprint id.
