Thanks for bringing this to my attention - it looks like the signup was broken due to changes in the Recatpcha API responses.
I've updated the module that we're using, but we still seem to have trouble with mail delivery (which contain the signup confirmations).
I've got our infrastructure guy looking into it, and will get back to you early next week.

For now, should I create an account for you manually?

Sorry again for the inconvenience, and to all other (unknown) translators who tried to sign up.
And again thanks for going to the trouble to find out alternative ways to contact us, you typically
have better chances to get attention by email than on the forum on these severe problems.

OK, the problems with Recaptcha registration and email sending should be resolved now. If you have applied between 20th of August and 8th of October 2010, your application probably didn't go through (and we can't recover it). I'm very sorry this was noticed so late, and would kindly ask you to apply again (Petr/WhiteGfx, I've already set you up with an account). Thanks!
