If I offer 1.5GB of monthly transferring on my client's accounts, is this just website to user bandwidth, or also client to website uploading etc (uploading their sites / files)?
I would imagine it's 1.5gb for everything. because jodohost has no way to know if the upload/traffic is from you or from just a website user. I have a page on my site that has an upload form for the users and I'm pretty sure this uses my bandwidth.
