@jamie. i would ue the template or engine for more than just pen testing by the way. As a mechanical engineer, i will be writing reports probably weekly if not daily.
I think a reporting engine will be awesome for more than just pen test engineers
as for calaborating, google docs is good at that. there is also a program like google docs but can be ran privatly on a LAN for a business(thought that doesnt help you but still pretty cool)
@ datadwarf. dude, you didnt lead us astray, just gave some awesome info of what not to do. This forums totally reminds me of a thomas edison style forum. try and try again until you suceed. I have found it is very importatnt to take notes like mr edison as well. if you get a chnace to see some of his writings, you will be impressed. he wrote everything down and i mean everything.
