This is certainly is not an original idea but I wondering if it might be possible to included gamertag tagging in posts? For example, I recently gave a s/o to a community member. I sent him a PM to let him know, but it would be nice if I could have simply just tagged him and he automatically received a notification. Same goes if you are responding to multiple replies in a thread. I could also seeing this being used for Destiny gameplay vids, simply tag all the gamers that participated in the vid. Is this something you have considered?
