Can I use the RSS app to read the posts off one of my own blogs on my website? If so, how?
Yes, you can. You can learn more about it here http://breezi.com/how/rss-app/
Update: This post shows just how to do it:
Show your Latest Posts on a Sidebar with the RSS App
When I log in and click on the apps tab it says its loading but it never does. Is there a way you can recommend making the site work faster or is it a glitch in the site perhaps?Thank you
