Don't you understand anything of what you're being told?
The idea is to keep MsgPlus!'s name clean, not make everyone hate it. And P2P stuff are bound to make some users angry.
And, btw, people use P2P to get big files (or warez), the only small files you can get are old programs or sound files (MP3, etc.). It's pretty dumb to use a P2P for MsgPlus! when it's only 3MB and it's completely free.
Yeah, it could be good for the server, but then again, no one would look for a file like that in P2Ps. And that's why there's a main site with mirrors and all. Because people don't go through the trouble of getting a P2P program and searching and waiting to download a free, 3MB program.
