Yeah, they're not the usual "go to this page, copy paste this there"-type of instruction.
 * Make sure you have personal javascript enabled in your Preferences.
 * Go to User:1033Forest/global.js

Since you don't use that yet, paste the following there: window.announcementsIgnore = { option: 'opt-out-all', exceptWikiIds: [ XXX ]

importArticles({   type: 'script',    articles: [        'u:dev:MediaWiki:AnnouncementsIgnore.js',    ] });

Where I typed XXX, you need to include the CityId of the wiki in question.

To get that, go to the wiki you want to ignore. Press Ctrl+Shift+J to open the console in the right side of the screen. Copy paste this code there: alert(mw.config.get("wgCityId")) and press enter. You now get a popup with the id. Paste that where it says XXX. Multiple id can be done separated by a comma.
