1. Other like the name denotes are simply additional blogger settings that did not fit into the already discussed categories, doesn't mean they are trivial anyway;as you will get to judge sooner
2. Adult content is where you will tell blogger your host,whether it should show warning message to your viewers first before opening the main page. Specifically for bloggers dealing on X-rated/sexually explicit contents. It will first show one of those ' note that the page you are about seeing contains hard/erotic materials, please confirm that you are up to 18 to proceed'.... It does not mean that you can't deal on those stuff without activating this program, but for the sake of morality and decency, I think you want to.
3 Open ID URL like in the above, should contain your site/blog address
4. Enable title and enclosure links: Yes. title links allow you give links to your post title on the post editor while enclosure links makes it possible for those that will subscribe to your post via feed burner to be able to, see videos and play mp3's when ever any post you make thats contains them are delivered to your readers
5. This is what you want appear after every post you have delivered to your readers through feedburner/email subscription. You can use ads here, that's Google adsense that generates cash per every click( will still come to this)
6. Post feed redirect is just similar to custom redirect talked about on search and preference settings. So look that up again. The only difference is that whereas the former is for your page readers/those that visit your page directly, this one is for feed subscribers. Those that applied to be sent your post after every publication.
7. Allow blog posts to show in full on your home page. Set it yes. Already you can use jump break function at the post editor to cut the entire post to any length you want shown to a visitor before ....,,''Read more''. I already said about this on post editor.
8. This should be Google Analytics. check at the last end of this other section,it's there. My snapshot couldn't cover it also. This is about having full track of your visitors. I mean, google analytics function will show to you every bit of information about your blogs traffic, ranking, and traffic source once activated. About the activation process, i think it should be a later problem. Let's set up a blog first.
