IMPORTANT ANNOUNCEMENT
Please, do not use built-in functionality, to back-up your wallet!
Most likely it will generate incorrect data and backup will NOT be usable.
You can backup your wallet manually. Files reside in ncc directory:- windows: c:\users\\nem\ncc\
- mac/linux: ~/nem/ncc/
There are always two files: wallet file (.wlt) and address book file (.adb)
I think this should be added to the OP (along with a statement saying it will be fixed soon) to make sure no one loses their NEM by mistake.
The OP contains only the information where all the information are found. Again: We did this because BTT doesnt give us the possibility to maintain the OP by more than 1 person.
Overview is here:
http://blog.nem.io/overviewI wish people would just read a little bit more... We can't repeat the same stuff 10 times a day.
I like the zen op

I think it might be worth copying that info from the overview onto the OP though.
Personally I like it as it is, but it seems a lot of people are missing some of the info.
The OP should at least say "NEM has a 100% original codebase and over 70 team members" to make people interested enough to click through to the blog.
Just my humble suggestion as a marketing guy.
EDIT: these would look very nice in the OP
