I need a red circle

Well sowwy :( some of us have to work! Just wanted to share the good news

Well this isn't that important anyway. We know HL3 is coming out, Valve themselves have basically said that they will just take a lot of time. Registering a trademark doesn't change anything, it would be obvious that valve registers even HL4 and HL5 just in case.

For me it seems like a bit of bad timing...why right now? Just seems a bit random for them to wait a couple years on it.
