Yup, I saw you on there :-).  In terms of the responses, you're dealing with a bunch of guys who tend to be some way down the autism spectrum and whose diplomatic skills aren't the greatest, I cringed a bit at some of them.  It's not negative, they're just pretty direct and blunt.  You may want to drop a hint about how painful it is to use a screen reader to set up a server and so you're relying on ones run by others, which will give them a bit of context and maybe moderate the bluntness a bit.
