It depends what you mean by "add someone." If you are a plaintiff and want to add another defendant, then you must seek leave to amend your complaint and file an amended complaint and have all parties served. If you are a defendant and want to sue a third party in your response, you can do that as well, under ORCP 22C.
If you are representing yourself in a lawsuit, you should be familiar with the Oregon Rules of Civil Procedure, which govern all civil legal actions in the state. You have the same obligation to understand and comply with these rules as if you were an attorney. The rules may be found online here: https://www.oregonlegislature.gov/bills_laws/Pages/orcp.aspx . If you have any questions, you should consult with an attorney in private.
