Alternatives to this module

I don't plan to work on it further. I did this for a site of mine and thought I share it if someone is interested.
If you are doing a better 'trash' module you can take over this project, I don't mind.

About the implementation: Having the status field as an indicator for trashed nodes is in my opinion the right way to do it (or add another 'deleted' flag if you rather have the status field only have two possible values). The 'status' field would be available for nodes, comments and users out of the box. This is much easier than moving the data into a separate table and move it back again. Of course such an implementation should be in core as the core modules define the possible values for the 'status' field.

By the way, do you mean this module http://drupal.org/node/219800 ?

yes thats the module and i try to make it but i got stuck at the nodes

About the implementation (2): The great advantage of this approach is that you don't have to handle custom data. The database of contributed modules is not affected and thus no special care has to be taken. Of course contributed (and core) modules should always check the 'published' status of the nodes they use or they accidentally show trashed data. That's exactly what I am hoping for in this module (at least the modules I use do it ;)

That module isn't even done 2 years later http://drupal.org/node/219800

There's no alternative to this module

Another approach would be to remove the role's "delete own content" permission, which will remove the Delete button and use the Publish Content module to provide easy unpublishing. You can view your "trash bin" with View Unpublished.
