I'm not entirely sure if it has anything to do with the new server, or anything that happened during the merge, but I've been going through some of the posts on my profile that people have made over the last couple of years, and I've found that strangely enough, every single one of them before the change is posted twice. I'm not sure if that's a benefit to you guys, or if that's otherwise what could be double the space being taken up that could be used for other data, but I thought I might bring it up. Seemed very odd. EDIT: This also applies to PMs.
Thanks for bringing that to our attention. It is definitely not intentional. I will add it to the list for our engineer to look at.
