I view regularly for inspiration, but do not post much, unless I can post something constructive or have a question on something. I also have interests in other hobby fields. I have seen the ''Where is everybody'' and ''Forum losing interest'' mentioned on many other forums, so this is probably just the nature of how forums work.
But what seems to be trending, at least I think so, is image hosting. Some sites, CSF included, are showing images replaced by a picture about ''Updating your 3rd party account''. Something to do with the set up of the image hosting services, and storage costs, (I don't know because I don't use them). This may have an effect on visits to the website to either view or post images of an ongoing project. Just a thought.
