With the maps from this forum.

Nope, Oh well.

Seems to be the maps from this forum..?
Quite a nice clip though... Who did it?
Well, seeing as you are a new member...and seeing that the video was posted today. I'm guessing that was you.
Credit needs to be added for the maps linking back to them.

Wait, so some guy made a teaser trailer for a mappack, or something in the sorts, using other peoples maps that he didn't make? And he didn't name the maps in the description which probably means that he didn't ask the authors permission?
Hopefully this is just me with another 
There are several clips of AngryBombs in the video, and the lack of given credit leads me to believe that the video's author is going to be releasing a...map pack of already released maps that he/she didn't create?
Not quite sure where to go with this one.
Now with 100% more inline comments!
Oh great, the plagiarism games have begun... This ALWAYS has to happen, doesn't it? The good news is, judging by the incredibly poor quality of the video, I honestly don't think this will be quite as successful as whatever fool compiled this sham of a map-pack thought it would be.
...wow, that was judgemental. Unnecessarily so? Perhaps, but I have a hunch with this one. Although, I'm also perhaps getting a slight scent of 'successful troll is successful' here.
I'm normally the first to crack down on someone doing something against the spirit of the community, but I haven't seen enough yet to take out even the warnhammer. Let's see what happens on August 1st and go from there, eh?
The trailer IS featuring my map, however no permission was asked and i wasn't credited...
Please take down the trailer and add some proper credits... after asking for permission!
I actually dont mind my map being included in a "best of the community" style mappack, but then please credit the users and ask them before just featuring them in a trailer!
now just to figure out who uploaded it...

... I guess I was stupid to think it would work...
I'm gonna take the channel down in a few days, so I might as well tell you what the idea was...
It was suppose to be some sort of weekly contest, I was to announce the map, and next week the person who finished it first.. um... would get somethin..
Before announcing the next map I was to video myself trying to do last week's map(with commentaries). And, obviously, failing miserably. I also wanted to show others' funny fails. (In a "fails of the week" style)
Just thought it would add a little interests, 'cause just doing map after map for no purpose can get boring after a while... and that's a shame cause there are some great maps here..
Ay.. Asking for permission... and credits... I haven't thought this through, I guess..

You win!
