Most on the online boards are dying a slow death. The move to Facebook and IG has really hurt the traditional sites where actual knowledge resides. I think you need to be inclusive of new topics and newer watches in order to keep the communication alive. 95% of the info on vintage watches has already been said and posted numerous times, and can be recalled with a search.

The only boards I am aware of as an exception are the Omega and Military boards, which seem to be ticking along nicely.
