I just received an email from Rod Tilyard (Koalastamps). He just launched Mystampworld , a new online community for stamps collector.
Since the brutal death of the MyPhilately social community (see my post here: http://www.kilowares.com/myphilately-com-website-is-no-more/), no other site has taken over the more social aspects of stamps collecting. MyPhilately was a great experiment and hopefully Mystampworld will thrive and manage to get were it’s predecessor was going.
Among the interesting features there is the possibility of having your own blogs there, groups as well. Trades and sales are probably going to be a strong point as well.
