And, just to clarify further, since I've noticed in my travels that people find this confusing: being "signed in" is not like, say, being logged into your bank's web site to view your account.
When you are 'signed in' to a PLP, there is NO active network connection between the file and you. You could 'sign in' from your laptop, save a draft, and then take the laptop on a trip for a week, come back, plug it in and do a send/receive.
The 'sign in' only has to do with letting the PLP know that someone (you) has reserved parts of the file for use and to record the number/etc (mentioned by Link) so that when a S/R is done later, ArchiCAD knows what to do with it.
The PLP keeps track of the 'sign ins' (really 'workspace reservations'). Signing out not only releases the workspace to other users ... but it also clears the PLP's knowledge of the ID assigned to the draft. So, after the signout, you cannot do a send/receive with the draft.
I'm sure I'm still not clear...dinner time on Friday!
But, another comment is that many people think they need to sign out at the end of each day, or before lunch, or whatever. Not so. You can stay signed in for weeks (although that would be a little odd)....because, again, the 'sign in' is NOT a network connection. It is merely a database operation that stores some info in the PLP, and allocates a draft file to you. I think if the command was "Reserve Workspace" rather than "Sign In", things might be a little less confusing?
