Jumping in late in the game here, but I'd like to volunteer to help move some stuff from the old examples to the new if it needs to be done manually. If we get the DB up and running we could have some people divide up the existing examples page into sections and work our way through, migrating any available information into the new DB. There will likely be holes in the data, but if the creator of those cabs have a chance they can update as seen fit. I suppose there would have to be some moderator level access to the entries and an owner level access as well, this way the DB can be filled out and then when the creator of the cabinet shows up and wants to update they can have access to their project.
This system sounds great. I haven't ever looked into putting anything of mine into the examples system, because it seems like you need a project blog or the like to link to. With this system it would be nice if the option was available for all the information to be hosted at the DB.
