But what I don't want is a restrictions on the number of files a user can upload. For example, when attaching files to an e-mail there usually isn't a restriction on the number of files allowed. Like hotmail for example (there is a restriction, but lets say there wasn't).
A user can browse for a file. And once a file is found then that file is added to a list. Files can be removed or added to the list via the single field on the form.
Does this make sense?
