[bcop] IPv6 troubleshooting for helpdesks document is now RIPE-631

Dear RIPE BCOP community,

With great pleasure we can announce that one of our first BCOPs in the 
works was few days ago published as RIPE-631

https://www.ripe.net/ripe/docs/ripe-631

Many thnx for all suggestions, comments and support during the work and 
I hope this document will be of much use to those operators, who are 
implementing IPv6 towards their residential customers (and also everyone 
else with similar task).

With this document published I would like to encourage you all to 
continue the work on other documents that are currently active and also 
others, that we heard about during our last BCOP TF meeting.

RIPE70 meeting in May is near and I hope for some advancement in all 
other documents in the queue so we can talk about some good stuff in 
Amsterdam!

Cheers and thnx, Jan Zorz
