Welcome to SfKchan
SfKchan is a classic-style imageboard. You can browse boards, create new threads by posting an image with a subject, or reply to existing threads. Registration is completely optional. If you post without an account, you will post as Anonymous.
Anonymous #ID System
To help users identify each other within a thread without requiring an account, all Anonymous users are assigned a secure #ID. This ID is mathematically generated using a one-way cryptographic hash of your IP address. It is completely permanent, which ensures that anyone posting from the same connection will always share the exact same ID, allowing users to recognize you over time.
Text Formatting Features
When creating a post, you can use several built-in text formatting codes:
| Feature | How to type it | Result |
|---|---|---|
| Greentext | > Be me |
> Be me |
| Underline | _Important_ |
Important |
| Click-to-Copy | Text&cnp |
Text (Copies "Text" to clipboard when clicked) |
| Combined Formatting | _Underlined_&cnp |
Underlined (Underlined + Click-to-Copy) |
| Auto URLs | http://example.com |
http://example.com (Clickable link with external warning) |
