People I shared my folders with cannot access due to "not enough space" - this is unacceptable.

From what I understand, I would have to send a fresh File Request every time they had new photos to upload.  That's a very clunky system and not what I'm looking for.  

My experience with Dropbox up to this point has been as an outside user having to upload and download files shared with me by large companies.  They create a folder and send me an invitation.  I had never had a Dropbox account of my own before.  I would create one, log in and be able to download and upload files in those folders which would contain considerable file amounts and sizes.  I understand they were enterprise level companies, but I personally never had anything other than a beginner level account. 

So when the need came up for my church to need somewhere for our users to share photo dumps larger than allowed in email attachments, I remembered how easy it was to use Dropbox.  But as a small user being the one to host the file share, that's not the case at all.  They really put the screws to small users trying to squeeze money out of everyone they want to share with.
