The ability to search for users by various criteria, send email and private messages to users through a template-based messaging system. International language support The XOOPS community has official support sites for non-English-speaking users. Additionally XOOPS itself supports multi-byte character sets for languages that use characters not in the Latin alphabet, for example Japanese, Simplified and Traditional Chinese, Korean, etc. The multi-language support is also available on the PDF generation feature provided by the TCPDF library. Theme-based skinnable interface XOOPS uses themes for page presentation. Both administrators and users can change the look of the entire web site by selecting from available themes. Templates XOOPS uses the Smarty templating engine which allows many benefits such as easier separation between business logic and presentation logic as well as content caching. Built-in LDAP authentication Some SEO add-ons A number of XOOPS modules contain features to facilitate the indexing of a website in search engines, like metatags, title tags and occasionally some URL rewriting. However, XOOPS does not give its users full control over their URLs. Where URL rewriting is possible, XOOPS often uses redirects that may confuse search engines. In addition, some XOOPS modules create duplicate content by making the same information available on more than one URL while in other cases (especially in case of multilingual sites), several sets of content may be made available through the same URL.
