+<h3>Q18. May I use .Net Framework?(2011/03/20-)</h3>
+<p>
+Tombo is developed by win32 API and don't use any frameworks.
+But it causes bad maintenancerbility, less extensivility.
+Using .Net Framework, I can develop more good UI, etc.
+In other hand, you have to install .Net for each PC that you use Tombo.
+Which would you like, good UI or portability?
