[Hps] Slack upgraded

[McCormick, Jeremy I.]

Hi,

We have upgraded the HPS Slack to the Standard plan.

https://urldefense.proofpoint.com/v2/url?u=http-3A__heavyphotonsearch.slack.com&d=DwIFAg&c=lz9TcOasaINaaC3U7FbMev2lsutwpI4--09aP8Lu18s&r=hGEVsUzUB5ml8iDt6EuOdg&m=f26hm2PEAeqUQysKMge2S7rBWctfBVFs20A4a04Qpv8&s=KOFw6rg95Ugqwkd6WEaPa8kC58EB_vWl0R9BN7EOyxE&e= 

This means that attachments will now be permanently saved along with the message history, making this application much more useful now to the collaboration.  It can be used as a permanent repository of information now.

If you are an HPS collaboration member who is not a member of our Slack, please send me an email, and I will send you an invite.
