Currently, a huge portion of the SL Wiki (especially the LSL documentation) is out of date or contains wrong information. There are also dozens of example LSL scripts that are ancient, not using current best practises and should be removed.

Additionally, there are thousands of links to the old JIRA which can no longer be accessed.

Even worse, residents don't have the ability to edit pages or even contribute to the Talk pages, meaning it's impossible to make/suggest corrections (which begs the question, why are we even using a wiki system and why can we log into it with our SL accounts? Are there some special non-staff users that have this privilege?)

Perhaps LL can allocate one or two employees to go through these pages and update them, consulting with relevant developers where necessary to ensure the info is accurate. Finally, allow residents to contribute to edits and discussion (Talk pages at the very least). If that's too risky, consider recruiting more wiki volunteers.

Update: I've just found out that the contents of the old Jira have been ported to https://github.com/secondlife/jira-archive so an automated Wiki script could potentially update a lot of these old links.
