Oh, i think we had a similar idea at the same time.
I just launched >>>/netplus/ for info/discussion of decentralized and anonymity networks.
This sort of content would also be welcome though.
I also set up a Retroshare+tor chatserver for us here udgdahofbq52bzxk.onion . You can find out more about it here >>>/netplus/3 and >>>/netplus/6 so that we can hopefully form a 'darknet' community that anyone can get involved in. I made a setup/config video tutorial so that anyone can get involved even without any /tech/ skills at all.
There are also a couple of write ups on tor and i2p and I will be doing more over the coming days and weeks on other technologies and networks and weeks.
