As a new-comer to the forum, and another 50+ female, I'd also hate to lose the site.
I think part of the reduction in new posts is the wealth of information already found in previous threads. For example, while pulling my hair out about the lack of toilet training success with our 5.5 month old darling (despite never having problems with it in over 24 years of owning boxers), I thought about adding a thread on it - but then did a search and found loads of ideas (ok, none have so far worked, but I keep telling myself she's young yet!).
That example also makes me think that we have a tendency to post problems and questions - perhaps each member could start a Pupdate thread where they post photos and note achievements - that would be great for those looking at getting a doodle and for us to look back on over the year's as a record of our own journeys with our doodles....and just think of all those lovely coat transformations we can see
I check the site most days - I'll do my best to contribute something at least once a week.
