Expert writing Tips

Best practice

Ensure the preposition 'for' is followed by a noun phrase or a gerund, such as "I've signed up for a course" or "I've signed up for running a marathon".

Common error

Avoid using "I've signed up for" when you mean you have logged into an existing account. 'Signing up' is for creating a new account or registering for an event, while 'signing in' is for accessing one you already have.
