Contribute to Perl 6, without huge startup costs
Do you find Perl 6 interesting, but maybe not very accessible? Would you like to contribute half an hour of your time, if it doesn't involve learning a few new languages and weird parrot assembler langauges?
Then participate in the Perl 6 contribution challenge. No sign-up required, and there will be one task per week with which you can actually help the Perl 6 users and developers without needing to dive too deep into compiler guts.
The first challenge can be done all in Perl 5.
Any questions? Then ask. And fire away.
