Due to an overwhelming demand from our fans, we have more codes for League of Legends skins from PAX Prime! We have two sets, each containing Arcade Hecarim and Riot Blitzcrank exclusive skins. Entering is easy! Tweet at us using the hashtag #LoL or like us on Facebook and make a post mentioning our current giveaway! We will run this until Tuesday, October 1st, 2pm CDT. Please read the giveaway page, which includes examples.
Don't forget that Leaguepedia is part of the Gamepedia community, and your number one community driven resource for League of Legends! Please see the Leaguepedia Help Page on how you can get started. Already a contributor, but looking to improve your skills? We have a new Help Wiki just for that! We also have IRC channels, where you may find both Gamepedia staff and community members!
Best of luck, everyone!
