Can Anyone (Frank?) remove all the spam messages in the Soil Modelling section of the message board?

In this way the message board is completely unusefull.

Dear All, I'd like to perform a 1D site response analysis using quad elements. Is it possible to apply the horizontal acceleration using the plain pattern command (converting the acceleration to a shear force) and the vertical acceleration using the UniformExcitation command? The recorders will retu...

the old manual is incorrect: pore pressure is velocity of dof 4

Is there an alternative to GID for 3D models generation?

thanks
