I've been using the techcommunity a lot and I have found it very useful. It's really good when you can say to your customer : wait a moment, I will ask my 50.000 colleagues.
Sometimes I use the techcommunity site on my mobile (Windows 10 Phone) and I noticed that the @ mention doesn't work on my phone. Is this a windows phone thing? Or is this something that can be fixed on the techcommunity site?
