Talk about your stash – starting it, filling it, tweaking it, maintaining it, swapping it, optimising it and finally moving it to a new home (and anything else as well) at these online communities:
Nappycino Forum (closed i think)
OzClothNappies Forum (Aust & NZ)
Australian Nappy Network Forum (a forum focussed on advocacy)
You will also be able to visit the general parenting forums who have a section for discussing modern cloth nappy.
