We are considering NodeBB as a replacement to our project mailing lists that are currently hosted by Mailman (also on Nabble).

Is there a way to have a setup where messages sent to the mailing list would be also synchronized to the NodeBB forum? This would help us evaluate both in parallel, and support communities of users who prefer traditional mailing list.

Does anyone has experience migrating legacy mailing list content to NodeBB? I know there are some forum migration plugins, but I did not see ones specifically for legacy mailing lists.

@julian no, this syntax does not work for me

@julian can you please give me some instructions how to embed those cards? What should I do to make it show as at the top of this thread?

Is there an alternative? I tried and failed find any github support plugins, seems like basic stuff is missing.

This plugin doesn't work for me, or I don't know how to use it properly.

Can you provide the usage example?

Hmm. I figured it out. My miniscule understanding of iptables does not allow me to explain this, but if I move the rule for port 4567 up in the chain, it works. I thought they should just be going down the chain rules. Missing something here. Anyway, the issue seems to be resolved. If someone could explain why - this would be interesting to know.

I am a total beginner of NodeBB, and have a very very limited understanding of system administration.

Nevertheless, I was able to install NodeBB on CentOS 6.5 (which involved installing a non-default version of redis, and by the way, it might help to say in the install instructions to start redis server before running nodebb setup!).

I am able to access my installation from localhost:4567, but not from other hosts on my local network. I think my firewall rules allow connections to the NodeBB port (see below).

Anyone knows what I am doing wrong?
