[Laszlo-user] Laszlo Development

[Francisco Jose Peredo]

Hi!
The Demo  doesnt seem to be running now...
Could you please add some screenshots of the demo application to the 
site? (I think that way everybody can see how the application looks like 
without having to worry about keeping it running always... after all I 
understand that as everything else, it need maintenance... and for that 
it may need to shutdown... but I would like to be able to at least see 
some screenshots to get an idea of what can be done)
Regards,
Francisco
