m-league schedule

/mjg/ players map

A map of the /mjg/ players. Find an anon near you and try not to stab each other. Well, this is mostly used for coordinating time zones during tourneys.

To add yourself to the map, fill out this google form.

Alternatively, you can send your zipcode/location, user name, majsoul player ID (at the friends tab), a custom icon (or what you usually main) and a short message at mjgrepositorie@tfwno.gf or preferably at the usual irc channel because opening thunderbird lags my computer so much and I check it maybe once a week.
