(This message is primarily for those who know what feather is, or do not need guidance to find out. That's why I'm not going to introduce feather, and will just assume you know about it already.)
Feather has recently seen a memory upgrade from 1 GB to 2 GB. As memory is the greatest bottleneck (waiting for CPU time is much better that waiting for memory/disk swapping), this means that feather can now handle more simultaneous users.
Many existing feather users have indicated that they are currently deprived of tuits to work on Perl 6, so that frees up even more resources.
If you think you could put feather access to good use, in any way to the benefit of any of the Perl 6 projects, please request an account by sending me an email (juerd AT feather.perl6.nl) in which you explicitly ask for an account. Make sure that the message includes your real name, preferred username, and what you think you will use feather for. Do not request an account by other means.
To answer the most frequently asked question: yes, playing with Perl 6 and reporting bugs (as unit tests) *is* a valid use of feather, even if you're writing "just" a simple wiki or IRC bot. And to answer the second most frequently asked question: Yes, using feather for discussing Perl 6 by e-mail (firstname.lastname@example.org; mutt and webmail are available) or IRC (screen+irssi and webirc are available) is also a good use of the machine.
Update: title changed to something more descriptive, per chatterbox request.
