Welcome to Sitepoint, @sugunasri;
There are many members here who - I am sure - have ventured down the very same path and can offer you great advice on your problem.
It would be very helpful if you can provide a bit more detail about your environment.
- Who is the host?
- What is the Control Panel?
- What forum software are you using?
- What language (PHP, Ruby on Rails, etc)?
Any other details about your system and set up would permit a more precise answer more quickly.
