i visited this site.but it has many different topics like
Nutrition & Diets
Coaching
Computers & Technology
Arts & Creative Services
Education & Tutoring
Business & Finance
Health & Medicine
Spirituality & Religion and many more.
there is forum where advisers or people who want to advise give their introductions and links of site also.and u can mention your charge also.this site is not new but very few people have used its service.but i think one should have specialised knowledge in any field to be capable of giving right advise to solve problem.
