hey not to tell you how to run your business or anything...but giving one line isn't really enough to get a feel for a persojn. I am not suggesting many many lines, but if i may....something like a page from a briefing. More than one sentence will allow you to better hear the person in question, and the abilities that they do or do not posess. Most of us who have sent files are serisou about wanting to do it, and to be honest, i would hate to see all of your hard work on this mod fall short in the area of voice acting because of an oversight.
To be honest with you, i don't think anyone would mind at all if you were ot delete all of the files that you have gotten and post something along these lines for us to do. i firmly believe that it will be of great benefit to you in the long run.
If i am overstepping then just tell me to go to hell
