Others have reported comms silence from this WG.
I got a reply from a 1st contact email on AW so I guess I was lucky. With some girls it can depend on what you put as the subject header and what you also put in the main email text. Stuff like "I need to fuck you!" will likely get you ignored (not saying you did that but as an example). I just put the date I wanted to see her, from her published schedule, as the subject and for the text was just friendly and polite (like writing an email to a colleague at work) stating when I would like to see her if available, no mention of any sexual activity I wanted to do with her. Took her over 24 hours but she responded with her number.
Sorry but I'm not going to pass on a WG's number if she doesn't regularly advertise it on AW (which Gia doesn't).
