sometimes communication over email/text can come across as cold/ignorant. the guy might just be bad at communicating/writing or just really busy.

i would write again asking your Qs... flagging that he hasn't answered them. or just give him a call and get a feel for him and ask your Qs! best idea i think...

i doubt it's a con but be sensible and as always when meeting anyone you've connected with via the net, take someone with you/let someone know where you are going. you can even ask to meet in a public place if you're really worried.
