The wikipedia text that you see displayed on our web site is a download from Wikipedia. This means that the information we display is a copy of the information from the Wikipedia database. The button above ("Edit wikipedia entry") takes you to the edit page for the article directly within wikipedia. You should be aware you are not editing our local copy of this information. Any changes that you make to the Wikipedia article will not be displayed by our site until we next download the article from Wikipedia. We currently download new content on a nightly basis.

Before you edit for the first time

Wikipedia is a free, online encyclopedia. Although anyone can edit or contribute to an article, Wikipedia has some strong editing guidelines and policies, which promote the Wikipedia standard of style and etiquette. Your edits and contributions are more likely to be accepted (and remain) if they are in accordance with this policy.

You should take a few minutes to view the following pages:

• Five pillars
• Policies and quidelines
• Wikipedia help contents
• Wikipedia Tips
• Editing help

Things you should know

How your contribution will be recorded

Anyone can edit a Wikipedia entry. You can do this either as a new user or you can register with Wikipedia and log on. When you click on the "Edit Wikipedia entry" button, your browser will direct you to the edit page for this entry in Wikipedia. If you are a registered user and currently logged in, your changes will be recorded under your Wikipedia user name. However, if you are not a registered user or are not logged on, your changes will be logged under your computer’s IP address. This has two main implications. Firstly, as a registered Wikipedia user your edits are more likely seen as valuable contribution (although all edits are open to community scrutiny regardless). Secondly, if you edit under an IP address you may be sharing this IP address with other users. If your IP address has previously been blocked (due to being flagged as a source of 'vandalism') your edits will also be blocked. You can find more information on this and creating a user account at Wikipedia.

If you have problems editing a particular page, contact us at rfam-help@ebi.ac.uk and we will try to help.

Information we would like to see added

We would value contributions that are referenced directly to the primary literature. Information on structure and function will be especially valuable.

Adding references is made much easier by this tool.

For a good example of what is possible in wikipedia, look at the Hammerhead Ribozyme entry.

Does Rfam agree with the content of the Wikipedia entry ?

Rfam has chosen to create Wikipedia entries for all of our RNA families and to open them up to community annotation. While the original Wikipedia article that we import was (in most cases) generated from Rfam annotations, the Wikipedia article you see now may bear little resemblance to that original text. The Wikipedia community does monitor edits to try to ensure that (a) the quality of article annotation increases, and (b) vandalism is very quickly dealt with. However, we would like to emphasise that Rfam does not curate the Wikipedia entries and we cannot guarantee the accuracy of the information on the Wikipedia page.

Contact us

The community annotation is a new facility of the Rfam web site. If you have problems editing or experience problems with these pages please contact us.

If you are interested in contributing to a wide range of articles relating to RNA, see the Wikiproject RNA page.
