Do you have lesson plans or activities we could use?
No need to try and work out MediaWiki.. no doubt your lesson or activity already exists somewhere. All we need is the URL to your lesson or activity AND an appropriate copyright license on it (CC By or CC By SA) and we'll do the leg work. Naturally we would attribute you and your work, but we can't use anything with a Non Commercial restriction or more. Please reply to this thread if you have something of use. Thanks.
