Contributing new shapes

[Tsoukalas Giorgos <gtsouk unipi gr>]

Hi
I am a new dia user and i believe it is a realy promising project.
I had to make a few of my own shapes (following instruction on the 
documentation)
for intergrated circuits. It is nothing much, but why not share them right?
Thats the whole idea behind open source software.
So my question is where should i send these shapes in order to be
included (if they are good enough) in the next dia version.
I searched the site and i didnt find a relative link. I suggest that
there should be a place where users can post their new shapes.
In case such place exists and i couldn't find it, please someone
send me the link.

Thanks
