Feel free to send me the alias you want to go by + your message + end your email with something like "post in the guestbook", at
I will manually post it here, and reply to you both here and by email if it was a question. If you don't want your message published that's okay, just don't end your message with the "post in the guestbook" line.
You can also post a comment in my Neocities profile, ending it with "post in the guestbook" if you want it to appear here.
I speak Catalan, Spanish, English and toki pona, and can understand a little French, so feel free to send your message in any of those languages.
