I already had a dropbox account and wanted to use it, so I downloaded dropbox to my new pc. I wondered why it wanted me to give a name to "my team". So I uninstalled and tried to make sure to chose the basic version. But again it asked me to write a name for my team before I could continue, so to be able to get going I just wrote some random letters. I could then see that this was wrong, that it was a business version and uninstalled again.
Today I then received an email from someone I dont know. He wanted to join my team ?? Wonder where he found "my team" and why it can be interesting for him to join a team called random lettes like 'asdfzxcv'
