I did do a business trial, but did not try to connecting to others part. I read the instructions and it looks so easy! I follow the instructions to invite and bring in the other members of the team and they don't get the invitations. I can send them the "secret" weblink and then they can view the files, but they cannot edit. Which is critical. I have read through the manuals, but it has not helped me with this problem. I am the owner, manager, coordinator, HR, chief bottle washer, and yes, I do all the computer stuff, such as it is. My team members know less about computers than I do. I have had to hold their hands through dropbox, skype, join.me, electronic storage, etc. I am pretty much self-taught.
Actually, now that you mention it, I didn't do the "business" trial. I thought I was doing the business trial, but it turns out all I was using was the personal part. It took several days and emails and screen shots to figure out that part. We had that part working, sort of, and then I moved the files over into the business section and set up the company and the groups and that is what isn't working.
My plan is to set up my secondary computer with its own personal wuala account and then try to work out the connectivity issues when I can see the recipient computer and fiddle with the different combinations and methods of connecting. If I learn anything new, I will try wuala tech support and wuala forum again.
I do appreciate your help.
