Actually, since the first post is over 1 month old, I don’t think even @kseniia_li can edit it, since Discourse edit locks old posts.
Two workarounds that we can help you with:
- A moderator can manually edit the post for you. However, I would like to first confirm with @kseniia_li that this okay with them.
- A moderator can switch the first post to a wiki (even temporarily) to allow you or anyone else (unlikely if the window is short enough, and disruption could be easily reverted) edit the post.
Another more cumbersome workaround would be to create a new thread initiated by @proskurius and move all the posts under that one.
