We call it data (file format) reverse engineering but, it is also bounded with software reverse engineering because you need to examine (if you have) actual software which creates, edits, extracts this file-type. Reverse Engineering Stack Exchange is not a forum but, it is most helpful community i have ever seen. Also, just a few active forums discuss reverse engineering topics and they expect you know some basics about this field. Most people don't want to help step to step reverse engineering to somebody. For resources i can recommend you Reversing: Secrets of Reverse Engineering to start. It discuss theoretical basics and practical examples of reverse engineering including your needs.
