Everyone i am looking for any good opensource projects so that i can develop my skills and help some opensource community.As i have seen that many opensource projects require us to work full time on them.If any body knows any projects which i can develop in my free time please post them.
I suggest you signup for some open source project DL and try to resolve bugs or user queries. This would give you some exposure and understanding of the project and you would be able to contribute more efficiently should you choose to join it.
Get the source code of couple of projects, Understand the code and try to fix a bug / add a feature. Drop the code to the committers. They will review and then it will be accepted. Since you are contributing for free, they may not accept. It should be according their code policy.
