Currently in Discourse the only way to save the whole discussion (topic) as a file is to press Ctrl+P and either print to PDF or close printing window and save the opened page with the browser (like with addons SingleFile or SavePage WE in Firefox). The same can be made by manual adding /print to the URL.
The main problem is that settings of the forum.qubes-os.org are very strict on this and does not allow user to open this printing page like several times (5?). And after that forum shows “You’ve performed this action too many times, please try again later” message.
Discourse is already quite bad for saving pages from it (due to dynamic-load behavior), but this additional limitations are making it even more painful.
Solution proposed: Remove or increase the limit of printing/saving pages of the forum for registered users. Limit should be like 100 in a row per day or something.
