Draft comments and fixing broken back buttons
I upgraded to v1.01 the other day and as a side effect the attachments extension prevented my users from creating new topics.
now i'm not having a dig at that extension at all but as you can imagine people weren't best pleased to type out a nice long topic and then only to lose it when the error came up upon submitting it.
it got me thinking... would it be possible to have an extension that would auto save the user's post into a draft.
much like gmail does so well.
if it is successfully posted the draft is automatically removed, else it remains for the user, safe and sound.
