Just log on to Simple Reach
Create an account with your email.
Confirm the account with the link that have reached your mail.
Add your blog to simple reach account.
After this there's a small change in the procedure what simple reach tell and actually is.
they will ask you to upload your template which u want to add the widget and after uploading they will ask u to download the template from simple reach and upload to your blogger blog. but after uploading your template u won't find any download link. So my suggestion is.
Upload your template, after that click on Manage link on top right of your computer screen.
You will find your add blog, there itself u will find an option get the code, now just copy the code and paste it just above
That's it, just be calm for few hours, simple reach will grab all your post and start up to show on your blog. Hope this post helped u all. Please let me know your opinions.
