I noticed that I cannot edit this meta question. The tooltip explains that
Suggested edits are not allowed on non-tag-wiki posts on meta sites
After searching I found this post and this post that says that this is by design. I do get the reason why I can't edit (not enough rep), my problem is that the tooltip explanation is not very clear to me. What exactly is meant by 'non-tag-wiki posts'?. Does it mean that if someone with enough rep adds a 'wiki' tag to the question then I will be able to edit the post?
