Well this was a bit much to read through..!
Idea seems fun and interesting enough.
I do think there's a difference between open forum for opinions, and people thinking that means being rude and a bit of a ***** to someone. Opinions are great and all, as long as you have common sense and common decency. It's not decent of you to pick apart a simple invitation post and make a big stink about it. You're stirring the pot of drama and you know full well it'll get the people posting back slightly frustrated over your obvious rudeness.
This is where it gets good, I love that people have opinions and can 'aid' others in seeing the faults of their posts or add new ideas. But being nit-picky and grumbling a big stink about this and that is just childish. Not much of an opinion or help to anyone. The only thing people learn is that some humans can't think before doing all that typing and pressing 'submit reply'.
If you don't like what is worded or how it's worded then, instead of jumping in and being a stinky turd, move on. Don't smear yourself across the post and stink the place up. Luckily I have plenty of wunderbaums!
