You can add a profile link to your forum user card. There’s an existing topic about that: Share the link to your Couchers.org profile!. The discussion there also explains why we didn’t make it more prominent so far, as it’s apparently not so fail-safe how to set it correctly. I’m lacking a good idea how to make it more easy now, but when we’ll implement single-sign-on, it can be automatically set.
In any case, if you open my user card and follow the link, you can see how it’s supposed to work 
…though I see you have it set and working on your card as well.
