The free element of Dropbox is pretty big and the more people join, the more space you get but at some point / capacity, it becomes chargable.
and then who pays for that charge and what happens to the files if the bill is not paid?
We sort of tried this already in a single thread called OUR CARS, but after a bit people lost interest.
I can install a GALLERY type of thing that is connected to the forum like the one here:
http://microcar.org/gallerybut after awhile, people lost interest in posting there as well. Now people just upload their pics to whatever thing they find the most convenient for them.
plus everyone would need new accounts for that area as well. Kind of a pain.
Currently RUMCARS incurs no charges for the domain name, web hosting or the forum because I am able to fold it into my existing account that is paid by other things.
Also- there is currently no actual limitation on the number of files that can be hosted on this site.
Just as an "Off Topic Lounge" was created, it would be trivial to create another separate area with different permissions than the forum area.
Anyone could start a "new" topic documenting anything they wish, with no one else able to add to it but the original person that created the "topic" (I'm pretty sure that will work that way)
In other words: Read only for everyone except the creator of that specific section.
I'm not saying that DropBox is a bad idea, but it is another thing people have to remember passwords for and for someone to maintain.
