I agree with Sammy, I do not want to be a wet blanket or dampen your enthusiasm for what at first appears to be harmless fun, which it is. But nowadays, and especially in your country you need to be very very careful about what you broadcast without anyones permission. With only a few exceptions ( toilets for example) you are free to post anything recorded in public. The same is not true for 'private' and it may be argued that although a server is open to the public, in general terms there is restricted access, and any players deserve a level of privacy. What you are doing, in legal terms, is recording their actions and voices without their knowledge, then placing this recording in the public domain. May sound excessive but be careful, things like this can go wrong very easily, at the very least make it clear at the start what you are doing , and if there are any objections, for your own protection. The free world disappeared years ago I'm sad to say, Harry Weezer will be nodding his head in agreement. Sorry Randall but you need to think this way, I know many do it, but mark my words someone will come to grief, make sure it's not you my friend. Don't stop ffs, but take a few precautions, it is not an idiot who will object, but not all players are idiots, and one could be a sharp legal eagle out to make a killing.
ps all you need to do before recording is to type in something like
'I'm going to film this round for Youtube, any objections?' better safe than sorry mate
