Thread:Project:Support desk/Adding New Users to the wiki

At our office we use this wiki to log troubleshooting methods and known fixes for all to access in the IT Dept. However our former manager who setup the wiki has left and we do not know how to add new users or grant new hires access to this page. We only have the logons that we have had all along. Is there an easy way to add users to our wiki, or any way at all?

thanks!
