Hello and welcome! Glad you found us! I also came to the GB manga after enjoying the anime. I wanted more of Ginji and Ban than I could get watching the anime -- and now I love both!
Things are moving along pretty well with the translation, so I think it won't be too much longer that you have to hold off reading volume 39.
In the meantime, there is other reading to catch up on -- and after you post 15 times in the forum you'll have access to the latest chapters hot off the press!
