I've been on this site for over a decade..I have changed name a few times over years but had a regular one in early years. I noticed someone else had created a new username virtually identical and most people would think it was same user at first glance. I ended up changing names and 'losing' my usual name.
It's just happened again. I've had this one for years and now there's another user (can only see posts fairly recently) who has virtually same name (added a letter at the end).
Shouldn't there be a way of making sure names are more unique? It's annoying.
