It used to be possible to subscribe and thus receive and email whenever blog content was updated in the community blogs.
The ability to have an email sent when content changes in the community blogs has been restored after it was lost in the big redesign earlier in the year.
I was recommending that Steve Endow @steveendow should be trying this feature to be notified of new blog postings, only to find that the feature was no longer available! After brining this to the attention of the team responsible, they have kindly restored the functionality. So if you want to know when a new post goes on the blogs, use the bell icon at the top of the blog as shown in the screenshot.
Configure notifications as digest frequency
To configure the email settings go to your picture at the top right and use the drop down to get to settings.
Select the Email tab at the top of the page, then scroll down to the email settings:
For each group you can change the frequency and nature of the mail from that group (blog).
