Just wanted to point out something to doctorbee and others who thinks paypal site does not look credible. I just went to below website:
 
http://www.help4crisis.com/houston/nepali-fire-victim/ 

 On the right had box, I see three contribution options. First and second looks to be paypal sites. Second one seems to belong to Nepalese Association of Houston paypal account. The 3rd option is to mail check to Nepalese association of Houston.

Hence, looks like you can use option that you find credible.

So, rather than arguing and pointing fingers send some contribution if you feel like it. If you don't feel like it, read a book or watch a movie and go to bed!
