Ted,
Good observation. Totally agree about the numbers.
Schoppy might be able to tell us how many "lurkers" are here in a month.
Personally, I think that those with only light incontinence usually move on after learning enough to cope with their milder problems.
However, I also think that many with more serious incontinence who could or should participate here are too embarrassed to do so for fear that their public discussion of their incontinence could be linked back to them.

That is particularly sad as many of those probably are the ones who most need to participate actively here. As we have learned, the recently incontinent usually are the most nervous about it.
Of the general population, consider how many are in denial about their incontinence and even refuse to use the word "diaper."
Remember too that some older seniors lack the online skills to search for and find this group. A simple Google search might produce a link to one of the less serious incontinence sites or even one of the fetish sites that would be a big turnoff for most seniors.
What do you all think about this?
