I just want to promote my suggestion that a PI System Administrator should be able to make announcements on the PI Vision start page. I see an urgent need for this myself, and I hope more of you see the need and vote for this suggestion.
Yes, I like the idea too! For any and all ideas that would make the PI System better, easier, more user friendly, etc please submit your ideas to https://feedback.osisoft.com/
Also note that if you reach out to OSIsoft Tech Support, we can submit ideas on your behalf (after first checking to see if it already exists), so keep that in mind as well. Why not fix an issue and get an enhancement request submitted in the same case?!
