Don't know where this question belongs. So here goes. I am building a vacation home distant from my primary home. I would like to create a website or a tool for efficient interchange between the contractor, architect and owner (me). 1) simple & inexpensive, 2) accessible via computer and phone, 3) post pictures, 4) upload (and download) files, 5) some text interchange for questions, etc. I am sure I could build my own website, but was hoping something existed out there. Any ideas welcomed. Thx
