ANet hold bonus weekends and special events with some regularity. For most of these, we already have information on this wiki that would help players make the most of that bonus.
I propose that we institute a page that holds the announcement of the upcoming weekend event and links to any resources our editors feel would be of benefit for that. The discussion page could have requests and questions.
After the weekend was over, we'd move-archive the page - or make the page for the date directly and redirect from the main tips page, that means we'd just have to edit the redirect and add the page to the archive template. The archive should look somewhat like the game updates archive, but we'd not show past events on the main tips page.
If a bonus weekend repeated itself, we could just copy & paste the old page (and add a link to that).
