As there is no question and answer section?

I am still a Newdie Critter Foal (replace with the young animal moniker of choice).
My question is, at which point can I start crittling as apposed to posting?
Do I have to wait to become a Forumite Foreman or can I start right away?
I've read the rules and understand I cannot post work until I have done my apprenticeship, but it does not mention crittling.
When can I do that, please?

 

Now.

 

Thank you, Madam.

 

3 days, I reckon.

 

I've got a tenner on 2.

 

What's crittling?

 

Immediately! Crittle away! I love it.
