As if to prove that there's no ill will against you Cyriel, I'm going to agree with you on this matter. If you need to be away from the cockpit for more than an hour, disconnect from IVAO and reconnect when you get back (as per the suggestion from the IVAO staffers on that thread).
But (you saw that coming, admit it) I'm going to put in a proviso... I'm not entirely sure of the numbers that are going to be taking part in the long haul leg, but it looks to be a good 5 or 6 at the minute. As long as "out of cockpit" time is kept to a minimum (under an hour), and when those that do leave mark their FPs appropriately ("away - XXYYZ to XXYY+1Z; reason"), and as long as most of us are still there and know who is away and for how long, I personally don't think the IVAO staffers will be too upset.
Now I have my IVAO forum login again, I'm going to post an event notification that makes it clear that for the T-A section chances are we'll all take breaks at some point to let "the co-pilot have a go".
