So in conclusion:
PM's OK (just don't expect a response)
Phone calls and Text not OK

As far as PM I have never sent out a PM asking for a date. I have noticed since moving down here that some times Gents will hint to a date via a first PM but, not ask. I have received PM's before complimenting me, or giving me advice (puppies or allergies) and noticed that he may be or was hinting to wanting to see me. I brought it up in a very classy way and I was in fact right. That was also after lengthy conversation via PM. That is about as far as fishing for dates I will go.
IMHO it is not classy and it makes your look desperate. Not trying to be ugly again just my opinion.
