I have also been looking around for mail art on other social media, including facebook, twitter, Pinterest and Instagram. Flickr is maybe the largest archive for mail art. A search for 'mail art' comes up with over 170.000 hits and there are quite a few groups dedicated to mail art. I have found a number of IOUMA members who are archiving their mail art on Flickr. I have also posting my mailart on a Flickr account.
Look me up at http://www.postmodernparcel.com - Instagram name is postmodernparcel ; I also have new twitter account - pmparcel.
Hello, my blog contains more then mail art work. Under this label you can find my letters and postacrds i made:
Not too much to see yet, but i am working on it :)
Am on twitter @iuoma , but somehow it doesn't brng me that much new ideas since I work on that many platforms already.
p.s. This ning platform is interconnected with Twitter. When you have an account you can send your postings straight to Twitter as a tweet.
In case anyone wants to participate in the letter-writing campaign to support the Catalan political prisoners, their addresses can be found at catalanprisoners.info, and the twitter for posting pictures of your envelopes is #DearCatalonia.
This is where I post most of my Mail Art works and other art: https://tigriseeufrates.tumblr.com/
