She insults pretty much everyone. She's like that, unfortunately. I almost got myself in a scuffle with her my first day here. >.>;
She's very good with the occasional trolls though.
But in any case, like I said, I missed whatever happened between you two. If anything, if she is abusing her mod powers, then just talk to any of the other mods or something. I dont know how RPM's admin panel works, but logs of that stuff are usually recorded on them.
Or, you could try talking to her directly via PM, though im not quite sure how much of a good idea that is, as I couldn't say how she would react to a NON hostile communication attempt, something serious, but it is an option.
Or you can try ignoring her, though i dont think that would be an effective solution for you in particular.
I dunno, its your call really. If you wish to leave for a while to clear your head and take a few deep breaths and come back freshened, that's also an option, but I cant solve your problem like you say. you have to solve it somehow.
