I am not a developer but can read code and update a little bit (but not much)

I am looking for a way that will allow community users viewing a Case, to "escalate" the Case. What I envision is that the customer clicks on a button called "Escalate", the customer would then document why he/she is escalating the Case and click Save. 
Upon save, a custom Case checkbox called "Escalated" would become TRUE, and the text written by the customer would display in the Comments related list (this last part is less important). The customer's text need to be visible to the internal users, obviously.

Thank you!
Julian

Need to be able to download customers emails (from email-to-case). We know it is not possible to download/Save Email Messages (*.eml, *.msg, ...). This is documented here:
https://success.salesforce.com/ideaView?id=08730000000Lj02AAC

I haven't found any App on the AppExchange to be able to download/save emails.

I have submitted a Case to Premier Support. Answer: "not possible, please submit a question to our Developer Forum"
