So I'm going to use logmein to support a customer of mine while she's on the road; the free version looks fine. However, I'm a little confused about the best instructions to give my customer. She will create an account, download the software, set a secret access code, etc. But it appears that she has to "invite" me to share her desktop? If she's running the client software and she gives me her secret access code, can I manage her machine without an invitation?
