Do-it-yourself social network platform GROU.PS has raised $1 million in the second tranche of its first round of funding. The new money comes from Golden Horn Ventures, the same firm that invested $1.1 million in the startup roughly a year ago. GROU.PS has features that allow users to create wikis, photo albums, maps, and calendars. In addition to running Google AdSense ads, GROU.PS has launched a subscription feature, which lets network creators charge membership fees. Network creators can choose to run performance ads, which people can then use to offset the cost of their memberships.
