W3C ORTC CG in Top 5

Thought some of you might get a kick out of knowing that our little CG formed in August 2013 is already in the top 5 for CG activity in the W3C.  (just barely edging out the competition)

2014 has been a banner year for Real Time Communications and 2015 will be even more exciting. A big thank you to our member participants for their continued support and contributions!

Happy holidays everyone.
