    Hi all,

    yes I agree ... and I was currently just talking about companies "using" plc4x. As quite
often I am asked: "do people use PLC4X" and I usually say: "sure quite a lot, unfortunately
I can't tell you who" ... so if we had such a list, we would have something to refer to.

    And yes ... let's discuss "products and services" separately ... here always a vote on
the PLC should be required.

        I would agree with Julian's position there and I think that this would further promote
acceptance in the industry.
        After all, the field of automation protocols is a rather delicate area in which trust
is an essential point.

        If this helps, I would also like to place my university institute or rather my employer
(my is such a big word :D ) as a user. But as Julian mentioned, I would only accept any entry
by PMC vote.

        I think we have to differentiate.
        If its just a "users" list or "powered by" list then its fine and PR is the way to

        Before we discussed about "companies that offer products / services around PLC4X"
which is a different thing. Here, I still am convinced that we should always do it via PMC
Vote to really ensure that no one "sneaks" in or someone is embarrassed that he is not on
the list or whatever.

        But I am +1 here (and would ofc place our logo there and get one or two of clients
of us that now run solutions powered by PLC4X)

            Hi folks,

            I like the mode the Airflow folks are doing it ...
            by not adding them manually, but only via PRs, I guess they are on the safe side.

            What do you think folks?
            Should we just create such a page?
            (I'm taking about the "who's using" list)

            If we had some use-cases or success-stories, I'd also like to have something like
that, but not sure if companies are currently willing so share stuff like that and just having
1-2 of them would probably be counter-productive. We could start collecting them and add them
to the navigation as soon as we have a critical mass of stories.

                Of course, I agree with Łukasz that this should be done with the
                consent of those companies. Probably best if done by those comapnies.
