I see that some couchers want the CS voucher system back. I have 1 vouch only on CS (and do not care about it at all) but I heard from other CSer and CS Ambassadors that the system had been changed due to the trafficking of vouchers among people that could distribute them (i.e. exchanging vouchers just to increase their number). And that some people with many vouchers ended up not being so great persons in real life after all. You probably know this better than me, but as a base (basic?) member I am surprised to see the suggestion here.
A feature I would like to see on Couchers is a calendar with the dates of accepted hosting requests being automatically blocked, and the option of being able to block future date that I do not want/can host.
Edit: the topic is here : Block calendar dates
