These are just titles that Andem(the owner of the site) created for people as they reach certain post counts. This also goes for the colour scheme that one has(the level of posts that Said1 has means that she has a yellow scheme). Both will change as your post count gets higher. For example, if you have over 10000 posts, your colour scheme will be purple.
Regarding the titles, you can personalize them if you wish(for example, I changed mine to Dark Overlord). They can be edited in your Control Panel. I do not believe the colour scheme can be edited. They can only change when you get to a new level of post counts.
I hope that answered both of your questions, mit and Said1.
I have to ask though, is that just normal feeling new to a new group stuff, or are you being made to feel that your contributions don't matter or that you're unwelcome?
I've been ignored in a couple of spots over the past couple of months and I have had some pretty nasty things said after I've given my opinion. I thought the idea was to give an opinion and have people either agree or disagree but not call me a Jerk for my thoughts or opinions. Why can't people just say "I don't agree with you"? Why does it have to be a name or a sarcastic comment? I deserve sarcasm because I believe the world was a better place when a parent (it was nearly always Mom's years and years ago) stayed home with their kids?
When I say I've been ignored, all I'm saying is that I've tried to join into a bit of a conversation or discussion but people on here who already know each other pass over the post like it wasn't there. By what I read, I assume that is exactly what they did in order to get to the post of someone they did know. I'm sure that myself and others as well may do exactly the same thing on canada.com and not realize what we've done. I guess it's not good for anyone's ego. However, life goes on. Thanks for asking though.
