Hello (^ ^)/
from time to time I am here and edit stuff. But mostly I use it to look up Parts and Planets because I can't keep them all in my mind. Especially the parameters for atmosphere calculations are not always present.
I've heard that there are some quite good tutorials on this Wiki. And even [www.wikipedia.org|Wikipedia] itself is very useful on topics of rockets.
If you want to see a real rocket launch then [www.SpaceflightNow.com|SpaceFlightNow] is quite a good source to get the dates for all life rocket launches. The stream the launches but I'd recommend to watch them on the website of the launch company. A selection is below:
[www.nasa.tv/ntv|NASA TV], they broadcast 24/7 all kinds of stuff. EVAs, news, education, ...
Launch Alliances (ULA)
On YouTube there is  who have a great number of launches.
That's it. Have fun .O/
