Nickname:
You can post anonymously by leaving the name field empty.
If you have an account with a nickname, you only post under your own account if you comment with your nickname.
This way, you can still post anonymously whenever you like.
Linking:
To prevent spam, all links are stripped out of your comment.
You can link internally to galleries, tags, etc. by typing an identifier (consisting of one letter and a number) between brackets.
To quickly find and select tags and galleries to link to, use the searchfield to insert them into your post.
