Welcome! I'm Jackie and I have two (maybe three, if my pending application is approved) of the characters running about here.
I have h_abbott and absoluteastoria. Astoria is a bit of a snob in her own right, but random interaction is always fun. She is engaged to Draco and they plan to marry soon in private, then do a public ceremony later when the weather - and press - are feeling less inclement. Hannah is engaged to Neville and the mother of a two-year-old (by a dead ex-boyfriend.) Hannah works at the Leaky Cauldron and is rather friendly as a whole, so there might be potential for (gasp) friendly acquaintances or friends there. :-)
