At DevConf.cz in June, OpenSuSE and Fedora booths were next to each other.
Fedora Hatch Meetup at DevConf.cz was chaired by Dan Čermák from OpenSuSE (he is also a Fedora contributor). You might want to ask him UK-based contributors of OpenSuSE if he’s aware.
p.s.) I have no capacity to help organizing events in the remaining months of 2024.
