The first of two meetings held today by Writers Guild of America leaders, presenting to striking WGA members the terms of a tentative deal they ironed out with the Alliance of Motion Picture and Television Producers, ended on a upbeat note, according to an insider.

A late-night show writer and Guild member who attended the WGA East meeting, held in New York at the Crowne Plaza Hotel, told that the presentation was received well, describing a ”mostly positive vibe in the room” and support for the WGA leaders and negotiators. According to the late-night writer, members seemed to ”recognize the warts of the deal but also found it a significant achievement.” As reported earlier today, the tentative deal offers writers some share in profits for content streamed and downloaded from the Internet, so long as that content is not purely promotional.

Most of the questions during the Q&A portion of the meeting, the late-night writer said, had to do with clarifying the mechanics of the proposed contract — WGA members only received details of the tentative agreement via e-mail at 3 a.m. ET Saturday morning.

A WGA West meeting will be held tonight in Los Angeles. The date of an official WGA vote to ratify the contract and end the three-month strike has yet to be determined.
