# Bidding System Help

{% hint style="success" %}
**Good to know:** we will be adding more systems and convention cards in response to Members' requests, so feel free to [**Contact Us**](https://bernardmageebridge.com/contact/).
{% endhint %}

This page is for information about **systems and conventions**. To start with we are including a file that has **two systems**:

* **a basic Acol system**
* **and a slightly more advanced Bernard Acol system**

By having them **here**, I hope it might **make singles** more able to **agree a system** which **suits their needs**. It also sets the **framework** of the ***‘natural bidding’*** of the **site**. As we **discuss conventions** on the **site**, I might **add some more files** to deal with them.
