I have some suggestions for the forum:
Several forums I belong to have areas (folders?) where files can be uploaded for the benefit and use of other forum members. I know files can be attached to topic posts but they are mainly to illustrate something in the topic. This is different.
There should be a place where members could upload catalog elements they have made themselves so others could download them and install them in their own catalogs. I'm sure people here have come up with wonderful things they'd be willing to share.
There could be another place for people to upload project files so people could look at how they are put together, and another for images/renderings of projects they want to show off, and another for photos of actual built projects designed with Env.
With regard to catalog elements there is a particular need for some usable furniture and furnishings. Users must have come up with some of their own because most of the furniture in the catalog looks like something you'd find in a second-hand store in the midwest in the early 1960's. Whoever came up with that collection should be schooled sternly by the queer-eye crew.
There should be a place where helpful link suggestions could be posted. For a start I would include these links:
