[Act] Act server: state of the situation

Hi Theo,

Don't get me wrong.
I don't blame anyone.
The Act-athon in Lyon was not the 1st attempt for a new Act.
I was hyped by Voyager but don't do anything by myself.

For the system aspects, I'm clearly not the best one to answer,
but what I can see is that mailman is consumming a lot of ressources
on phantom.
I'm about to restart a plan we had years ago but that we were not
able to setup because of technical issues (that have been solved in
the meantime): having the mailing list hosted by Sympa (rather than 
mailman) somewhere else (my current target is Strasbourg University).
I just had the info it could be feasible.
I'll let you know.

KR
Laurent

I mean, Act only talks to the Postgres DB, isn't it? That can be on any machine with sufficient power or even in a Master Slave.... and we could have multiple Act' servers in their ow tiny VM talk to them? right?

I assume that you can write down the procedure on how to do so. Guess an extra pair off hands will be welcome here. I was already planning on setting up a 'server down alert'
