Thanks for bringing this problem to my attention. I performed an investigation and found it was the result of an intentional change by developers the Discourse forum framework we use, which was introduced to Arduino Forum by the latest automated update:
The "My Posts" link in desktop sidebar will now be "My Drafts" and only appear when the current user has existing drafts.
I was able to find a way to circumvent this unwanted change and the "My Posts" link is now back in place in the sidebar menu.
Since it is only a peripheral feature, I moved the "Invite" link to the hidden area of the menu that accessed by clicking the "More" menu item.
I don't remember whether that "Invite" item was always present in the sidebar, or if this was another change introduced by a recent Discourse update.
Yes, the new "My Drafts" menu item is only displayed when you have post drafts. I think this is a useful feature, so I left it in place.
If anyone is bothered by the presence of the "My Drafts" menu item cluttering up their sidebar, just delete any drafts you don't have any use for. If there are drafts left that you plan to complete and post, the menu item will serve as a useful reminder to do that and once you have completed the post the menu item will disappear from the sidebar.
