If you have some spare time in the next couple of weeks, the Parrot TODO/skip test review is an embarrassingly parallel milestone which is suitable for anyone who can read code written in Perl 5 and skim code written in PIR.
All you need to do is pick a test file not listed on that page which contains either TODO or SKIP (capitalization does not matter) and list it on the page, with a count of the affected tests and a marker whether there's an RT or TT referenced in the reason.
You can mail the Parrot developer list directly or tell someone in #parrot on irc.perl.org.
Reviewing one test file is a help. Reviewing more is wonderful. If you have five minutes, you can do it!
