Judging from my experience, if your project is considered useful, people will start sending bug reports and corrections on their own. If this happens, contact your representatives, offer them write access to the code base, and share responsibility.
This way you will learn a lot about coding and, more importantly, team management.
What, saying, why don't you participate in existing projects to improve your coding skills? Reading the code of others will increase your capabilities much more than just writing your own material.
