just talking to myself - but confirmed it does. I tried Dave's app earlier - wriging there - routes to my blog - which syndicated to BlueSky - amongst others - and safely arrived. As did a reply from Masto - back in.

Was wondering if RSC was going to behave the same way - and it did - full round trip confirmed. Well 'full' is foing some heavy lifting there - more testing needed - but need to work out first what I am testing for :-)
