Add a wiki (which means "quick quick") to create a group authoring area on the website, for a shared writing project or knowledge base. Wikis are web pages that are grouped by subject, such as Policies and Procedures. They enable quick, collaborative development by allowing more than one author to add and edit articles. Subscriptions allow members to keep up with changes to a single wiki page or the entire wiki.
Moderating wikis without restricted authoring
Keeping wiki authorship open to all members is best in terms of maximizing the contributions and inclusion of others. If your organization has concerns about incorrect or inappropriate information making it into a wiki, see if moderation by administrators cannot give you the protection you need, as they have the power to correct and delete such content.
To work in this way, be sure that administrators are subscribed to the specific wikis in question, so that they will be notified of all page submissions and can respond promptly.
To create a wiki
1. Open the community where you want to create a wiki by clicking the community name in the community list.
2. Click Add a wiki.
If you do not see this link, you may need to be made a Wiki Author by your community administrator.
3. Define the wiki.
If you enable Restrict authoring to Wiki Authors but are not yourself a Wiki Author, you won't be able to edit the wiki.
4. Click OK.
5. Click Subscribe if you want to receive email notifications of all changes to the wiki.
Edit Wiki window
This window defines a collaborative work space similar to a wiki where community members can create and share articles with the community.

Select community link > Add a wiki
■ Name - Specifies the name of the wiki.
■ Body - Specifies a description for the wiki which is listed on the Community home page. If you find some features of the HTML editor confusing, you can download user documentation for the editor.
Note: Some features described in this external document have not been enabled for use when defining communities.
Caution! If you use the HTML editor's built-in Image Editor to modify an image that has a transparent background, the transparent background will be replaced by solid black pixels. If you need to edit images that have a transparent background, you should save a copy of the image to your local computer and use your preferred image editing program to modify it. Then upload the new version to iMIS again, overwriting the old version if desired. The easiest way to save a copy of the image to your local computer is to right-click the image shown the Preview area of the Image Editor, and choose Save Picture As.
■ Graphic - Specifies the graphic that displays in the upper left hand corner when the wiki is displayed.
■ Graphic Alt Text - Specifies the alternative text that appears when the chosen graphic cannot be displayed or when you hover your mouse over the graphic.
■ Allow HTML in posts - Select this checkbox to enable the HTML editor so that wiki articles can have HTML in each. If this checkbox is cleared, you enter plain text when creating articles. When you enter a URL, iMIS automatically creates a link within the wiki article, even if this selection is cleared.
■ Allow attachments to posts - Select this checkbox to enable a poster to attach files separately to a wiki article, such as a PDF document or an image.
