Well in that case, I'll just drop off my suggestions here:
Instead of tags, could quote, or bolds, or strikethroughs appear as though they've worked? By that I mean, I get to see them as how they would look like when posted before I post them (I know I know, I'm not good at explaining). For reference, there's serenesforest.com. Again, sorry for my bad explaining here, so I hope you understand what I'm trying to say here.
