there are/were a few, some mentioned above. also essentialislam, i think its called the problem is that very few questions are answered and its very slow. a few organisations/websites have tried but it hasn't worked out. need a team of scholars to work together for this to be sustainable and successful. wahabis/deobandis have had theirs for a long time. i hope dawateislami can get this sort of thing rolling, they already have the whatsapp service to answer questions for people of all countries.
not sure if this site is active, but they have some Q&A here: http://www.islamiccentre.org/ask-an-alim-mainmenu-88 On a side note, can you post the answer to your question here? I'm curious as well.
I need a website where I can ask fiqh questions. Does any one know the fatwa for permanent hair straigtening? JazakAllah
