This has been addressed on other parts of the forum, but I thought it would be worth bringing up here a couple of solutions.
1. When someone signs up for the first time, in BIG BOLD FONT stress the importance of each rider having their own account.
give reasons like giving feedback to individuals not to a group, future rides you may not have the same partner, your paths go different ways. ( two guys I hosted earlier this year did that when they hit the west coast , one north to Alaska
the other south to California. )
I just reviewed the FAQ section and there is no mention one way or another about 2 or more on a profile. The example
of for " what to put in my profile " is certainly written with a solo person in mind.
But since this is an ongoing issue maybe just tweaking the example to clearly state that each person should set up an account might help head off any issues from the get go.
2. create as easy ' link each other for this ride only' feature so that for potential hosts they can review each person without too much hassle. Also make it just as easy to ' unlink ' when the tour is over.
Just an engineer's thoughts on a perfect summer day that I am stuck at my desk job for another 55 min.
