Feature Request - Pin posts from different servers for yourself

Hi

This is a feature request I would love to see implemented. I'd love for there to be an option to pin a person's post for yourself, and for your own viewing, no matter what server you're in. The amount of times I've asked for help on different servers regarding software etc., that are full of hundreds of different conversations, and I've not been able to save/pin the conversation of mine, or a specific post/link. I've had to go manually searching based on my username instead. Most servers don't allow you to pin anything for everyone; only moderators can, I think. So being able to pin your own favourite posts/links that only you can see would be super useful.

Thanks
