# Why can't I post?

You need to hold at least 10,000 sub coins in order to post, reply, and upvote.

### Posting in a sub

To post in a sub

* Make sure you have at least 10,000 sub coins
* Tap the sub from Home tab
* Tap on the sub card below the price chart that says "OPEN"
* You should see the subforum, with a "+" button in the bottom right corner

### Previews

If you don't hold 10,000 sub coins, you can preview a sub once every 12 hours.

However previewing is view-only – you cannot post, reply, or upvote.

### Posts tab

The Posts tab shows you posts from all the subs that you're currently a member of. It is primarily a consumption experience – you can reply and upvote from there, but not create new posts.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.subs.fun/why-cant-i-post.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
