One of the key issues for a successful online community is trust, and one of the biggest ways of building or breaking trust is people's user names.
Could you all use your real names, rather than nicknames.
This is a key part to the success and professional image of this platform.
When you create your profile, it is CRITICAL that the content is in the form that you would like Google and other search engines to find:
YOUR NAME must be in the form you want to be found by - i.e. Rory Murray, not "rory.murray" or "R Murray"
Your profile must clearly describe who you are and what you do - using any key words that are critical to your job, your company or your research areas.
