OK thanks. Explaining my steps, if I log out of WU, I'm just a random guest. I went to the WU WunderMap and manually found my camera as an ICON on the map. When I select the ICON it shows the automatic ID generated. Remember I am still logged out and just a guest so everyone should be seeing what I see. I logged back in and checked what was entered for the neighborhood and it is not that ID but the description I wanted. Guessing I just don't understand but it's not worth beating my head against the wall. Anyway, for this topic the issue was that the wiki links are broken in WU webpages.
WU_534531's is not a camera ID. that is the login ID that was used to create your Weather Underground account. As such all your cameras will be associated to your login ID. You may have gone through some automated weather software program process to create your WU login ID and that is why you are seeing WU_53431 as your login ID as it may have been done automatically through that process. I created my WU credentials manually on WU website. As such currently there is no way to change your login ID.
Here is my WU camera on the map showing my WU login ID not camera ID.

Once you click on the user ID then you can see all of the other cameras that that user has. Notice the names of the cameras are still not the camera ID, they are showing up listed with the Neighborhood name for each camera.

You don't have to use the Neighborhood name to be a real neighborhood. You could use that field to give the camera a name. Some people use things like direction (Facing South), or they use the name of what you are seeing like Lake Cam...etc.
