Hallo Martin,
|
||||
|
||||
John und ich könnten leider nur am Freitag, da wir Donnerstag und nächste
|
||||
Woche bereits Termine haben.
|
||||
|
||||
Wir würden uns dann den Freitag vormerken...;-)
|
||||
|
||||
N Screensharing ist bei uns leider nicht so ohne Probleme möglich, bzw.
|
||||
wir könnten einen PC aufsetzen mit nem seperaten Internetzugang auf dem
|
||||
wir ne VM vorbereiten könnten, da wir von dem "Internet PC" nicht auf
|
||||
unser XXXX zugreifen können. Falls ihr sonst noch irgendwas benötigt
|
||||
einfach kurz ne Rückmeldung...;-)
|
||||
|
||||
Grüße aus Bonn
|
||||
|
||||
John & Marc
