I was able to find over 1000 files that were missing from the new MaplePrimes. I did some spot checking and it appears that the vast majority of files are now intact. 

I did see some posts where the files are still missing. If I come across a backup containing additional files, I will restore them as well and post about the recovery here.

Due to Joe Riel pointing out comments missing from that thread, I looked into the MaplePrimes migration process and discovered comments that were missed during the migration process.

I am currently running a process to import additional comments and answers. This means that the recent page will be filled with older posts as comments are being imported. The process should complete in several hours, after which the page will return to its normal behavior.

I have just published a new update to MaplePrimes. This fixes a number of issues and ads a couple of new features.

• Autocompletion of tags now works. When you are typing a tag in, a list of possible completions appears, you can click or arrow down to select one of these tags.
• We have added a new Products list. This shows all Maplesoft products that have Posts or Questions associated with them. This link has been added to the top bar, the Tags link has been moved to the "More" drop down. 
• The ordering on the Recent pages has been fixed to sort by last action date descending.
• You can now view tags such as 2Dmath
• Paging has been fixed for many sections of the site including the tag details page
• If you choose to upload files when editing an item, the new file will now work correctly.
• If you choose to convert your Comment into an Answer, you now have the ability to choose the correct parent for that comment.

I've seen a few people talk about how they are bookmarking /recent/all instead of /recent/unread. I wasn't sure why they were working this way, but realized they might not realize how /unread works.

/unread lists all Posts and Questions on MaplePrimes that you have not viewed. Once you click on one of those items, it no longer appears on the list. However, if the item is updated or a comment or answer is added to the item, it will re-appear in the /unread list. This means that by checking /unread, you will see everything that is posted to MaplePrimes, even if it posted after you last viewed that thread.

I believe the confusion was that items don't re-appear in the /unread when replies are posted, so people were viewing /all so they could see everything. I hope this clears things up.

I just fixed several of the MaplePrimes badges. Two of the badges, 2-Dimensional and Historian weren't being awarded when they should have been. This has been fixed, and now two people have earned the 2-Dimensional badge, and 91 people, the Historian badge.

I also updated the text for the "Popular Post" and "Popular Question" badges. They both now state that the question needs to be viewed by over 1000 people. The number that is displayed at the bottom of Posts and Questions is the total number of views, so refreshing the page counts as another view. To earn the badge, 1000 unique IP addresses need to view your Post or Question. There are several items that have almost 500 unique visitors thus far, so in a couple of weeks, the first people will start earning these badges.
