Updating an already submitted hashtag is quick and easy. You will simply resubmit the hashtag again. Before you begin, make sure to visit the hashtag’s page in the Healthcare Hashtag Project so you can gather the information you will need:
The original formatting of the text of the hashtag when you submitted it (uppercase/lowercase, etc).
The Twitter account you used when you first submitted the hashtag.
The Category assigned to the hashtag.
The image below indicates where those last two items are located when you visit a hashtag’s page in the Healthcare Hashtag Project.
Now you are ready to re-submit. Click here, and:
Make sure you submit using the same Twitter account as you previously submitted with.
Make sure the hashtag uses the same category.
Make sure the hashtag has the same usage of upper and lower case.
