Happy new year to you Ken and all fellow Hub users.

Q: How can I subscribe to all (future) notifications like this one?

I assume if I click the follow link on this article, then I will only receive updates on this particular one.
I want to receive all future similar notifications like this "consolidated GTAC Knowledge Articles" for a particular week.

Very useful to see them all in this weekly format, than having to scan through all articles on the KB.

Thank you for the question, and glad the list of new articles is helpful for you! You can follow one of the 3 categories that I always put the list of new knowledge articles: General Wireless, Network Management, Switching & Routing. If you have email notifications enabled then you will see the new topics, and the weekly list of new articles will be one of those.

Thank you Ken,

I was actually hoping that one could get just the summary articles and not every one of them not all articles are applicable to the infrastructure deployed in all cases.

So, the lists is a handy 'filter' in order to quickly see which articles would be interesting/applicable to our environment. I imagine there are others with similar views.

In the absense of this, I will subscribe to the 3 topics.

Thank you for the reply.

We are hoping to have more options similar to that in the future. The knowledge search in the Extreme Portal has some improved filtering options, but we do not have a way to highlight newly created articles there yet. Stay tuned to the Hub as we will share any improvements here. thanks for the feedback!
