I'm trying to make a page where the member can modify part of it (but without logging in the back end). For example, I'd like member to be able to change a text in a specific part of the page or change one image by uploading his.
I don't want him to be able to change anything else, nor the page style.
What would be the best way to handle this. I have started to search and one of the potential solution could be to use custom fields to define what would be modified in addition to front end editor.
If you have other ideas, I will be very happy to learn from you.
