Ugh, I wish I could edit the post, but I can't after some short amount of time. I have been thinking more about the names thing, and I think I misrepresented my opinion on good names.
In general I think new, inexperienced doms should think about names that are
- Capitalized
- Sound masculine/dominant
- Don't include any vulgarity
- Don't include any English words that are explicitly dominant (Master, Dom, Trainer, Owner, Whipper, etc)
The numbers thing is more an issue where it seems like someone couldn't get the name they were looking for, so just tacked a number onto it to get an unused user name. It feels lazy, and I think names are too important to be lazy about.
