Not sure who to mention here since Robin answered Colleen.
But here I go:
Colleen is a person that is trying really hard to defeat me in every way she possible can imagine. But I always have a counter-attack and she yields, just for a little while and then she's back on. Overall I like her and she's probably the one I have had most contact with on this forum.
Robin is someone I haven't talked to very much here so far. But I've seen some of her posts and she seems like a generally good person too.
