How often are new chapters released? The info says the series has been around since 2003 but it has 94 chapters. That is a little more than 1 per month, so am I to assume this is a monthly manga? The info says it's still ongoing even though the mangaka has a new manga, so I am just interested if this is still an active manga.

from wikipedia

The Nagasarete Airantou manga began serialization in the January 2002 issue of Monthly Shōnen Gangan, published by Square Enix. Additional chapters were serialized in the magazine Gangan Powered, but transferred to Monthly Shōnen Gangan after Gangan Powered was discontinued in early 2009. So far, sixteen bound volumes and one "guide book" containing various background information have been released in Japan.

Monthly Shōnen Gangan is released at the 12th every month.

Wow, how hopeless am I? It didn't even occur to me to check out wikipedia for information. This site is generally the only manga resource I use for info.
