Hello! We don't like spam registrations here! All new members will be moderated. User accounts that have been created but not verified through e-mail will be deleted after a week or so. I recommend you fill out fields like "interest" during registration to NOT look like a spammer. You have the option of leaving a phone number.
New registrations are disabled while an attempt is made to stop the spammers. We should be back up making kits very soon! : ) 2/26/2018
