Concert Reviews.
 

I know this might not be the place for the suggestion, but I was thinking that I'd be cool if in the Official post of a gig, the thread maker did a reply saying "Space reserved for reviews" and after the concert he edited that post with the reviews of the forum users (not magazines/newspaper reviews) that attended to it.

I'd be nice, as somebody could search the topic and have all the information on the first page.
