Dear new user,
we are very glad that you want to register an account for the CP2K-wiki. This will allow you to edit pages without getting bugged by the captcha and also your username will show up in the page's history.
We want to make it as easy as possible to contribute to cp2k. Unfortunatelly, due to heavy spam attacks we were forced to close the regular registration form.
Please send an email to email@example.com in order to obtain an account.
