Hello, I'm new to WordPress and I just started my own blog a few days ago. I installed a different theme and I was wondering where exactly you can edit the HTML code to add more links to the nav bar and add in google adsense and stuff like that. Any help would be great. Thanks.
Look for the files in your theme. Depending on the theme you might have a sidebar or other files that can be edited and you can always check the index as well. If you want to put your Adsense directly into your posts, there is a plugin at the WordPress site you might want to check out.
Hmmm.... did that help you or not? If not, let me know. I'd be more than happy to explain the exact steps to take in order to do these things....
