Can we also get a PM sent, notifying you submitted a report with a link to the post.
The second suggestion could be useful to the members before they hit 300 reports in identifying which posts they've reported.
Sometimes I go on a reporting spree and do ~30 reports in the Altcoin/Off-topic board. Meanwhile, Welsh has almost 30k reports (which means that he would have received 30k PM in his box).
Sorry, but this isn't a good idea. Hitting 300 good reports isn't that hard.
