I have some questions related to Blogger/Blogspot.com. How do I - a. search other blogs on Blogger? b. merge Adsense with my blog background from the UI perspective? c. change the size of my header block box? I am not a html expert. It's something in the #header css d. receive email notification of replies to my comments posted on other Blogger blogs, without paying for an upgrade to ProBlogger service?
