Putting up posters is all very well, but they seem to get taken down pretty damn fast too - well before people actually get the chance to note details etc. Same with bus stops, i've seen some places where the posters stay up for days and yet ours get taken down after a night?
Tried the Warwick forums and Facebook too to no avail!
get ones with the tear off slips. and tear a few off to make it look like some people are already interested... Board in Humanities doesnt get cleaned to often. Library face and chaplaincy get done pretty much every day.
And if you want a specific housemate then obvs go for a specific department noticeboard..
