I just got sent a link to this, which sounds pretty interesting, so I thought I'd share...
"Zineswap aims to be a resource through which people can swap their zines with one-another.
It also aims to become a vast archive of contemporary zine publishing, existing as both an online catalogue and an annual exhibition.
We are looking for contributions from people that self-publish their own zine or magazine. Content is not limited in anyway, your zine can be about anything."
