He's got fewer than 5 (or is it 10 these days?) posts from this account, that's why he can't paste full links.
A good way to get that post count up so you can post links would be to browse some of the other threads in the clinic and give feedback on other people's mixes. That will also make those people more inclined to listen to your songs. (It's a give and take relationship.)
It also helps to post one song per thread. Any feedback you get posting your entire soundcloud is likely to be pretty unfocused.
