some questions about the functions

Hi! I’m finishing up editing my site but there are still some things I don’t understand. If you help me I would be grateful!

1 – After registration, once I have redirected people to the activities, I would like the “homepage” to disappear because I use it only as a landing page. it’s possible?

2 – In the activity page I would only like photos, videos, posts etc. so no news on new friendships, new articles, etc. How can I change the type of content that appears on the activity page? I also saw that the comments appear one after the other and can not be hidden (screenshot1). Is there a way to show them only if the user wants, for example with a drop-down element that opens and closes?

3 – Is there a way to redirect people to the registration page when they click on the registration button at the top-right, without showing the pop-up? (screenshot2)

4 – I did some tests and I saw that the activation emails arrive in the spam folder. How can I avoid it? Also I do not want to send emails for any news (approval in groups, comments to photos or accepted friend requests). So how can I change e-mail notifications?

5 – how do I add the privacy policy in the registration form so that users have to accept it?

6 – I don’t understand how the matching system works. How can I customize it? is it possible to make compatible users appear first on the “members” page?

7 – I added your theme to my WordPress.com business account that I had previously purchased, so I can not change the file manager. Are there any plugins or other ways to add new codes like the one for advanced search in the members directory? Your support page about advanced search.

I thank you for your support! 🙂
