WankD............... looking through your reviews you have managed to post links there, on occasion, and some you have ended up with just the adultwork/search link.
I'll give you the benefit of the doubt, I know it can be a real pain on a phone as well. Particularly for those of us with fat fingers.
So, bottom of the profile you have the where they are based and age stuff, look there and you'll see a line that starts "Link to this Profile Page using
External Link/Members Only.............
Highlight the bit from https right through to the numbers (that's the profile number).
Right click, select copy
Then right click again where you want the link shown in your message and click paste.
