Is it a smart decision to invest Rs. 5000 in shares?

I have limited knowledge about the share market. I have been studying the volatility and sensitivity of the indian stock market for 6-7 months and I believe I have a fair knowledge about it. So owing to my limited knowledge and minimum risk appetite I would like to invest Rs. 5,000 in stocks. Is it a good decision? How big is the risk of diversification and transaction cost for such a meager amount? And I am investing with a short to medium term perspective ie my number of transactions might me more which would mean I will have to pay more transaction costs. Considering all that would mutual funds be a better option?

Also can anyone please also suggest of any investment forums where queries related investments are answered "free of cost".
