Original sentence: ‘‘Please remind me of posting these letters to my relatives.’’

Concept/Approach
After the verb ‘‘remind’’ used for future/forward-looking tasks, standard English prefers the construction ‘‘remind (someone) to + verb’’ rather than a prepositional gerund (‘‘of posting’’). This makes the intended action explicit and natural.

Step-by-step evaluation
by posting — Incorrect meaning; ‘‘by’’ expresses means/method, not the content of a reminder.to post — Correct infinitive of purpose/content after ‘‘remind me’’ → ‘‘remind me to post’’.for posting — Awkward and unidiomatic after ‘‘remind’’ in this sense.No improvement — Retains the nonstandard ‘‘of posting’’.to be posting — Progressive infinitive is unnecessary and odd here.

Verification/Alternative
Idiomatic models: ‘‘Remind me to call.’’ / ‘‘Remind her to submit the form.’’

Common pitfalls
Confusing ‘‘remind (someone) of + noun’’ (e.g., ‘‘remind me of summer’’) with ‘‘remind (someone) to + verb’’ (an action reminder).
