what nonsence? sorry to be rude, but a forum is hardly the kind of thing you can have offline. but there is a way:
install a new browser exclusively for digit forums.
give it a lot of cache space, say 3 GB.
browse every single page of this forum.
enable working offline.
voila! you have digit forums offline!
I wish you the best of luck trying this
I feel good that I did a good deed by showing the impossible to someone.
Astalavista Baby!
