I saw the FR MultiTeams server running Univermag and it did fill up. Sadly I joined too late but in this case after the custom map finished the server emptied quickly. I am sure there is room for a custom map server (or mixed). Let it be in Classic mode please though.
I wish the 40-1 server would add some custom maps into rotation. It is mostly the same core group and I am sure most of us there won't mind the download. The return of the TOGA server would make my day as well.
Yeah this is the only server I play on (named as TooL) and I'd love some custom maps to be added to the rotation, I'm quite bored of all the current maps.
