Daniel Stahl left Cryptic Studios and Star Trek Online duties about two months ago to join social gaming's Zynga. According to reports, however, Stahl has rejoined Cryptic a mere ten weeks after leaving. He will be returning, according to Gamasutra, in a senior producer role managing the Foundry.
That is why I'm excited to be back at Cryptic working directly with the highly talented UGC team to begin working on future updates for the Foundry, especially with the development of Neverwinter which has its own deep history of User Developed Content.
