Thanks you all for the kind words! I will continue doing what I love to do and helping others. Guess what! I just received yet another donation of $1.5! http://www.kavoir.com/weird/donation.jpg It's so minor but it really feels great. I'm gonna build more and more lovely and useful websites for people! You should do it too!
People tend to donate for a good cause (to maintain your sites, in this case), if you don't have other means to earn money (like displaying adsense ads etc.) but check whether you can survive only on donations or you can monetize your sites by displaying ads.
Even $5 can count towards something and can invested in something . How many of you have received donations? ~ Mike
