This is a list of active projects, that:
a) systematically find problems in the Wikipedia, and b) produce lists of those problems, and c) ask contributors for help in fixing those problems.
So if your project is:
a) active (i.e. you have a current outstanding list of things that need fixing) b) systematic (e.g. problems are found using software, not by humans) c) produces lists of specific problems (that preferably can be fixed quite quickly) d) would benefit from help from contributors
... then please add your project to this table, with a link and a brief description.
