Novices and Newbies
Novices and Newbies is the largest forum discussion group on Fetlife and is tailored to answering questions for new explorers of BDSM. The group itself is only available to fetlife members, however account creation is free.
The group is self described as:
We're a discussion group focused on topics relating to being new to kink and BDSM and for discussion of various aspects of the community and lifestyle that are important for novices and newbies to understand.
While there is much to learn in the BDSM wiki, the caretakers at novices and newbies will be able to answer lots of questions that require more subtle judgement calls than can be remedied through a wiki FAQ article and is especially useful as a resource to those that aren't sure which questions they should even be asking.
