yeah, the free account has a limit, but I’m okay with a small account - 5GB of transfers/month and 9/month is okayish for the subscription.
They also offer SSL encryption for an additional 9/month but I don’t require it at this time.
I like it because it’s scalable for multiple file uploads (up to 15 files), and also allows custom forms for uploads. Also, the sender gets a reference number after submission to track their files / correspond with receiver if needed.
It’s a pretty simple idea actually, and I can prolly write this app and run the server myself if I had the time, but unfortunately I don’t. I don’t know why no one else has thought of this yet - it has potential in scenarios such as document workflows for bids / RFQs etc.
