It depends on the implementation, but most are similar. For the on-line web page Garmin/Active Captain implementation, click on the feature, then on reviews then at the top left of the review box there is a "write review" box to click. Then a box open where you write your review.
On the AquaMap implementation it is similar but after clicking on the i for the information and reviews there is a pencil symbol that you click on to write your review.
I don't know how to create a new feature in either implementation. I tried and couldn't find a way to do it.

On Aqua Maps you can only insert a review of an existing POIs.
Activecaptain website is the right way for a new one.
I figured out how to add a new marker. With a clear chart, ie no markers selected, click on the little arrow on the left of the screen that brings up a list of available markers in the view. Click on add marker and it opens a box that lets you select from a list of available markers, drag a pointer to where you want to add a marker, name it, etc.
I knew it was there, just needed to scratch my head for a while to find it.

Are we using the AC app? I have no little arrow on the left.
No, I was using the online version with a web browser. No app. All nav apps are different. As discussed above AquaMap doesn't let you add marks, it only lets you add to them.
Maybe you are using a tablet app that is a Navionics product. Don't know about that one.

I'm using the Garmin ActiveCaptian site online. You'd think that it would be intuitive to add a marker. Used to be. I'm still looking for a solution.
