We completely understand where you're coming from but still hope there is a bit more patience left in you whilst the core developers work their magic on making Flarum stable.
I am in the same boat to a certain extent and really cannot wait for stable either. That doesn't stop me from using the software now because if anything bad happens, we have an awesome community here with members specialising in a variety of fields ready to assist.
That's one of the best things I take away from this community so getting to stable is just an added bonus! ?
