Hi, I use the Google Help Communities and sometimes when I am out of home i may use a mobile internet key that not always work fine (fast).
During my Flarum test i see if a member of Flarum write a post than press Post Discussion than the software is unable to post because of the internet connection week, the button to retry to post is no more enabled.. so the post went lost.
In the Google communities after some times (for example 2 minutes) if the post is not able to be published, the button to post it are re-enable and user can retry to post. Usually one or two time and the post is published and not getting lost.
Can you please check the Flarum code for see if we need add the same functions here for prevent post lost when there are internet connection problems on posting a content? Also "Save Changes" when a post is edited should work on the same way.
