we have a very similar system here in Italy.

Nice!

looking at the high number of access requests, in the end, the actual number of OMs whom is using the system is very low. Many of them looses interest or request the access just as a "nice to have".

That is always a bit of a problem. People ask for a certificate, connect to the server and then they think "well, what do I do next?" or "what can I do now that I cannot do on internet?".

There are some information sites having small lists of sites that can be visited and some search engines, and I have proposed to setup a more standardized and automated website to find running services and a description what they offer, but I do not consider it my task (as an address coordinator and admin for part of the systems) to build and maintain that. Others can pick up that part of the work.

Without a clear description of what we can do with the network, it is not surprising that not everybody keeps using it.

But it looks like you have quite some connected users too! Good!
