The site is currently alpha, meaning that when the full completed beta comes, it'll be more or less similar to the old OMGPOP.
To the people that stuck through and helped the site retain its population and usage, there should be special little things like tags, frames, colors, profile extras, etc. that shows that those people were here for the early start. Who knows? This site might become very popular like OMGPOP was, and it's always awesome to see people with those "limited edition" or some other special things that they could show off later.
It's quite cool to show others that you were a part of this since the first start and everything. I just thought it'd be nice to add some exclusive features for the early testers of the site(which is currently, you guys!).
