If several people at your company use MTI Film products or support them, its probably better to each create your own username here on this forum.
The reasons for doing this is that there are many built-in features for tracking what you have and have not read, as well as for sending notifications when posts you create are replied to or when you are @mentioned.
If you share a username, you are likely to find that its more difficult to keep track of what you have and haven’t read, etc.
If you want to follow a conversation that one of your colleagues has started, then its best to open that topic and set the watching status to ‘watching’ or ‘tracking’ so you can get notified and/or see when it has new unread posts.
