Thank you very much for your prompt reply!

We'll try this solution, which should be perfect for our needs :-D.

Right now we have submitted a proposal to include a Robocode workshop at 
Madrid's Science Week (https://www.semanacienciamadrid.org/). Our idea is 
to see how much public and competitors we can gather, so we decide whether 
to move to the next step or not.

And, if you don't mind the spam, I'll be very happy to share any updates 
with the group. Maybe here there are potential participants as well!
