This is the best website I've ever seen for downloading mangas! It's updated regularly and actually downloads. I just have two suggestions that might make it easier for readers/dowloaders.
1. Some sort of rating so that readers will know how "violent" or "sensational" the mangas are, because some summaries might make readers wonder exactly how graphical the series are.
2. Somehow indicate when the series is completed because some people like to download completed series.
Other than that, keep up the great work!
