(From keithhoff@imail.party) 
Hello,

I have not received an update regarding measures you're taking to combat COVID-19. I hope you'll assure us that you are following all recently released guidelines and taking every precaution to protect our community?

I'm very concerned that countless young people are not taking COVID-19 seriously (ex. the Spring Break beaches are still packed). I think the only way to combat this 'whatever attitude' is by sharing as much information as possible. 

I hope you will add an alert banner with a link to the CDC's coronavirus page (https://www.cdc.gov/coronavirus/2019-ncov/index.html) or the WHO's page. More importantly, please consider copy & pasting this Creative Commons 4.0 (free to re-publish) article to your site (https://covidblog.info).

Without strict measures and an *educated community*, the number of cases will increase exponentially throughout the global population!

Stay safe,
Keith
