Drupal 8.x

OK, this is a long one.I'm trying to work with/around some legacy links such as http://example.com/legacy-link/

I'm getting fed up of copying to root of my site all the time so want to move the /legacy-link/ folder into the /sites folder to make things easier in the future. Its an old html site but needs data to be read from that location

I have created a blog system in Views, and use a taxonomy vocab to add categories to blog posts. I have PathAuto'd the taxonomy terms to /blog/category/[term:name], and have created a page display in my View to use path /blog/category/%

I also turned off the default Taxonomy term View that comes with the base D8 install. This had the effect of leaving me with a page at /blog/category/[term] that shows the term as the title, but does not show the View. How do I get my View to show?

I am a developer and will likely be creating a module and/or contributing to existing modules. I know I'll be spending a decent chunk of time solving this, so am looking to the community to help point me in the correct direction.

Requirements --simple

Allow users to subscribe to things on the site to receive emails and see a list of things they missed via views on the profile page.

I recently found that unlike Drupal 7, D8 has a different form id for addition and edit of nodes. Is there a specific reason for that? Because this makes the hook_form_FORM_ID_alter() less granular as we now have to alter like mymodule_form_node_form_alter() and put the specific node type in there.

Sorry, could not find a discussion on this. Must be something very basic that I missed.

Thanks

Hello!

I'm new in Drupal 8 development, and try to create my first custom module to add a select option element in the update-manager-install-form form, for installing new module in "/custom" or "/contrib" sub-folder.

Personally i consider it as big security vulnerability if form in import module isn't validated in any way because user can upload anything and this can be harmful to a website or even hosting service. Is it standard behavior in drupal developers community? Before module become contributed does it go through any sort of check if it meets some specified terms, restrictions, regulations or just any module can become contributed without any check?
