hilarious that comment about 'copying my design concept'.... i think when we started at cardiff we were told on day one that it was unlikely that anyone would ever have a truly original idea and therefore not to worry too much about 'concept theft'. i think a few of us got a bit paranoid about in 2nd year, then realised how absurd it was, third year is a lot more collaborative - we happily let people copy our work, share site research, precedent studies on the grounds that time's short enough anyway, so if we can share ideas, spread the workload in anyway poss, that's got to be a good thing. and architects copy stuff all the time, and there's only so much you can really copy and be convincing with...
but i would agree with the earlier comment about the intimidation of architects hitting a bar en masse. it was like that a few weeks ago in cardiff - 30 third year architect suddenly arrive, take over the best part of the bar.... it can be a bit much.
