If the dev is so gently to let us know what he's doing....
A simple post like "I'm testing",or "Release is postponed next week" is appreciated.
If he say that will work on week-end, than the week-end he will not post nothing....
During week he post and fix problem and say that the most work will be done on week-end.
During week-end he will not post anything.....

It's not hard to log-in and write a couple of line about development that all community is waiting now,even if the week-end is almost finish.
