Hey, have an epic replay you want to share? well then heres where you can do it, post any replay you think is a good watch, no matter the league (bronze, silver, gold, ext), aswell as get some feedback on it.
to locate your replays go to /Documents/Starcraft2/accounts/(number may vary, check them all)/XXXX number/Replays/Multiplayer or Unsaved, if you didnt save it
Upload them via Rapidshare/Mediafire ext, or a replay hosting site such as Sc2replayed.com or SC2replays.com
Post the link and your all set.
