will the big youtube screens be more of an annoyance? they take up space on the post, that people have to scroll through.
Big screens? The videos only take up 425x366, and we've asked only 2-3 clips per reply. So it doesn't really take up all that much space.
and how big are these files. I mean, will they take extra time to load, like big pictures?
It shouldn't take long to load the youtube window(s) on the page (obviously pressing play the loading time will vary, but that's your choice) and there shouldn't be any impact on load times on the forum.
We'll probably introduce more options in the near future, with more streaming sites included. But for now, you'll have to make do with what we have.
