My inbox is still showing 2 unread messages when all are read. (same since first day of update, unsure if everybody is showing wrong number still or not).
You may want to press the button on the inbox page to mark all messages as read ...
I actually had an ad at the top of the page to see my PMs that said "View New Messages"...... duh! I almost fell for it
You can always tell the ads - they have the little |> symbol in the top right.
The other easy way to tell is to ask yourself "would simon have put that much effort into a fancy graphical button and a downloaded app just so I can read a message?"
The answer is no. If it looks fancy then it's fake, LOL
I can't foresee ever requiring a download to use the site. The only case would be if I created a native mobile app to read and post with but there would be a separate explanation page for it.
In general, if you are downloading something to install on your machine then you should only be doing it from a specific download page that tells you all about what it is and who has created it etc... If that page isn't from this site then it's nothing to do with us.
