Just join in if you want. Also, you don't have to officially sign for three reasons: the list is getting quite long so we don't need that many people signed up; you can still help out but you don't have to sign up and also, if you do sign up you're expected to help out regularly so it is better off to just help out autonomously if you're not sure you will be doing it regularly.
