Right now I set ours at 1.5 and it seems to be louder. Although I've started to question if it's "clipping" now. I haven't looked at any docs for Mod shout etc so it could be written somewhere.
Also 100% agree with you on the docs. I get that people need to make money, and Mark and the team have made a great product... BUT, huge BUT so much is "held" for paying customers, etc. It used to be the glorious class you had to take and would get the extra info.
I feel like certain things, like upgrade information between versions, how to keep your sever updated with out breaking things and for god's sake, settle on a -stable- release. It has been YEARS since an actual stable release has been released.
The reccomendation is to use master, which i have now resorted to, but I don't like it that if I install today and then 4 days from now there are changes etc.
