I have seen in other thread that there is a wp plugin for a particular single post to stay on top like a sticky post. Am just curious if there is an option/plugin for blogger too? Thanks!
for blogger change the post date to future.while posting .follow the stuff in links bellow http://bloggerfordummies.blogspot.com/2006/03/how-to-make-post-remain-at-top-of-page.html when that date comes..again edit that post and increase the date (i'm not sure of this editing but try..)
You can also go to templates make a new widget in the sidebar. Select text or HTML/JS as widget type. Write the message that you want to stay on top (this can be used as a welcome message because it doesn't include post date and author), then move this widget at the top of the blog posts widget in the templates. Save it and you are done. Thats how I placed the search box on my Game Videos blog. This could be your post that you want to stay on top.
