I've used these kind of cfg's on my old 4.1 server and I think it'd make our servers more "special" than others if we implent a plugin which automaticly executes a cfg which inserts the players name in it and welcome him in a special way. Idk if its possible but only show him the messeage since for others this could get annoying :)
I guess its not spamming if we use privatebigtext.
But im a bit worried that this might be a problem for our poor b3 if multiple players connect at the same time. (We already have some command delays from time to time right now...)
And ofc we would have to write the plugin which may be difficult. I dont know if i can do it, but i can try.
