[Zope] contributed zclass

i bet that a lot of people has their own collection of zclass. why not we put up the zclasses at zope site, so that we don't reinvent the wheel. it doesnot matter whether the classes are too simple or too <insert your own adj here>. if it's a class, put it there. i'm still too new to start my own product, but i've suceeded in creating a LinkCollection class, whi ch would take me more time if i did it in perl ( but i'm not going to throw away perl :)) it's not much but it's usable. (it's a class within a class ! mind you :) ) so, what say you guys? p/s - or is it there somewhere in the members area?
