Hi All, I am new in Mediawiki...I have few questions: 1) How can I integrate or embed msword's ppt, doc, excel into wiki text? (like iframe in frontpage and how to link that file) 2) How to open a file server's file in a new browser window which linked by file protocol? and is there any graphical interface extension (like windows file->open) to open file servers file and link in wiki text? 3) How can I create "email this page to friend" function in every wiki page like BBC web page. 4) How can I give permission to a group whose can edit only mediawiki:sidebar? Might be very general questions, sorry for that..but please I need the solution... Thanks in advance. Regards,
