If you are logged-in to the Wiki when you look at the "Recent Changes" page, and see certain listings that are bold, they are the ones on your "
Watchlist". It is not a sign that you did anything wrong. It is a feature of the Wiki that you can use so that you can more easily notice when a page-of-interest has been edited (by you or anyone else).
When you are logged-in to the Wiki, you can add any of the Wiki pages to your
Watchlist by clicking the "Watch" button (in the left navigation column). If you no longer want to have a page on your
Watchlist, you can navigate to that page and click the "Unwatch" button.
You can also use the "
edit" link to edit your watchlist directly, instead of having to navigate to each watched wiki page and clicking the "Unwatch" button.
P.S.: If you have a lot of pages on your watchlist, then the "edit" page probably will take a long time to load.
Hope this helps,
