I've probably been around in xda longer than most of people in this forum. This is not innapropriate and has been done many times in the past. People would post "BOUNTIES" in order to get several things to work on a device. In instances it would pool to a decent sum. If the forum rules have changed or not, i dunno, but there is no reason to get upset about this subject. Heck, you get Dual SIM to work. I'll chip in too. I've donated in the past, wheather it be cash, soda, or beer.
