And this implementation will also have some downsides. Will this have a effect on past posts? I'm pretty sure most users will lose most of their activity.
I myself would. And yet I'm fully for it.
I don't think that this is the case. I mean, theymos could just turn it off from now on and I don't think it should affect the past posts. Even if it does, I still stand by my opinion.ć
Also users like Xialla, many of the mods and current trusted members will downgrade to a lower rank
No. As long as you've posted in other sections in the time periods you should be fine.
Cool, but are everyone up for it?
There has yet to be a single valid reason not to do this.
