My node running in repeater mode does not flash the RX/TX/ERR leds.

Well it came to me. Rookie mistake.
The defines for my alternate LED port pins was listed below the MySensors.h include statement and not above it.
Once I corrected this error, my traffic LED's blink happily.

I can confirm YFandS's findings.
My node running in repeater mode does not flash the RX/TX/ERR leds.
The same node running a gateway sketch happily flashes the LED's.

Cheers.

I may be able to give a pointer towards this.
I am, as I type this, a first time user digging into the MySensors universe in search for knowledge on how to get a reading (from my first ever mysensor) to pop up (on my first ever mysensor compatible controller).

And what I frequently found a little frustrating was your site navigation.
It somehow manages to hide some of the good bits -- or probably more correct; the item names in the top and side navigation bars does not always give me a sense of direction when I go information hunting on a given subject.
And thus I sometimes simply fold and head to the forum only to discover there is a page for the exact topic - which I just could not spot from the navigation bars.

I can not tell you if it is just me or if others feel the same.
In general your site seems very thorough put together and maintains a consistently high level across the board.

Alas I have no solution to offer per se, other than maybe there could be some more cross-linking directly between pages, or perhaps adding tags to each page as iot-playground.com does, which is really helpful when narrowing down which pages could be relevant to visit next in search of a solution.
