Hello Sylwia, and thank you for your feature request regarding the ability to edit posts and tag friends in the SL feed. This is a great idea that could enhance user interaction and content accuracy. Interestingly, another resident had previously brought up a similar request about editing feed posts. We have found this duplicate in Second Life's previous bug tracking system (BUG-232371) and will be merging your comments to help prioritize this feature. While we don't have an estimate on when it might be implemented, please keep an eye on future updates. We appreciate your input and hope you continue to share your ideas to help improve Second Life. Thank you!
