I was AFK for a couple of weeks, so it wasn't possible to provide all of you with an earlier update.
Anyway, I got an answer approx 1.5 weeks after I sent the e-mail, which is pretty bad by 2005 telecommunication standards...
I was a bit surprised to find out that I must have misread the signals (the signals I thought she gave out, that she might be interested in keeping contact). She wrote "Thanks for the coffee offer but I will have to decline, I am sure we will see each other around though, the town isn't that big!". Well, that doesn't ring very optimistic, so I dropped it.
Although I don't mind that much, I'm pretty bummed at her formal "declining the coffee offer". It's just coffee FFS, how innocent is that? I mean, it's OK if she's not attracted and all that, but I wouldn't mind getting to know her better.
Anyway, I'm kind of diverging, so I'll cut the report here

Thanks to everyone who took the time to give me some insight!
