Currently not. Only mods & admins have this ability. You can keep some posts as your favourite ones by bookmarking them. That’s the reason of a bookmark actually.
yeah thats what i thought. But this could be a nice feature for example our service is for investors to talk about specific stocks and every topic is for some specific stock for following whats happening to the stock. And it would be useful to pin some interesting topics for yourself. https://keskustelut.inderes.fi/
I also have plans at some point to allow you to pin bookmarks to the top of your http://meta.discourse.org/my/activity/bookmarks list, because that list is currently sorted by the updated at date for each bookmark.
Would it be possible to also add this option to the “other” bookmark list? Bookmarks topics - Discourse Meta This list is a bit more on par with the latest list and more easily accessed (at least for those who have the link in the navbar).
