In the past, I deleted members who had registered 6 months or more previous but had yet to make a post.

Because we were 'rushing toward 1,000' members, I've stopped doing that.

There is definitely a period of time when new members become active, then their interest ebbs. Having an individual active for years is very rare.

Perhaps not being linked from the Harbour Lights site has cost us new members and thus activity.

I'm open to suggestions that might increase participation.
