In Depth Study of today's Dharma Teachers teachings

Does anyone know of any site on the internet (or elsewhere) that studies profoundly and carefully, the works of Dharma teachers? Like Mahasi Sayadaw,or Ajahn Chah, or any Dharma teacher for that matter? For instance, Mahasi Sayadaw's book, "The Progress of Insight" can be hard to comprehend, so what if a teacher got together with a group of students to study such a book of teachings in depth. Perhaps something like the following: Each pertinent sentence might be studied one by one, the translation of each sentence might be scrutinized, the scriptural origins would be analyzed and each sentence might be made better understood with real examples of what is meant. I'm sure that sites such as these are out there but I for one have found that they can be hard to find. I put **"today's Dharma Teachers"** in the question here not because I wanted to exclude answers about in depth studied of older teachings. I would like to know of these in depth kind of study groups no matter how old the teacher or teachings are. I suppose I thought that if I didn't put **"today's Dharma Teachers"** that the answers would consist of the more common study of older teachings & teachers and the newer teachings & teachers might be overlooked. -Metta
