Ack, should be fixed

Why do you think "hold" should be "token_hold"?

"token_retransmits_before_loss_const" - yes, it is long. Why do you see 
it as a problem?

> The description states "...retransmit and hold will be automatically  calculated...". Shouldn't that be "token_retransmit" (also see my earlier remark on "hold")?

Yeps

> For "token" the page says "Reforming a new configuration takes about 50 milliseconds..." shouldn't "50 ms" be "join timeout"?

Nope, but I can agree comment should be reformulated.

>

Ack

> "... which stil guarantee...": "still guarantee"? Maybe try a spell-checker ;-)

Ack first part

This seems to be just fine

RRP so almost ENOTCARE, but I will happily accept patch.

>

Ack
