Big_John: When you open that first email/message from a new person who hasn't ever contacted you before "how should it start?" What should it include? What do you put in it to him/her? Can it be too short? Too long? Which ones to you respond to and which ones do you delete?
It can definitely be too short. "Hi how r u?"......is not something I'd ever respond positively to, (if I responded at all).
Any endearments from someone I don't know is a surefire way of being blocked.
IMs from someone I haven't talked to in e mails previously, is a no-no too.
I usually respond to e mails that have at least 3 or more sentences in them, preferably worded without the use of text shortcuts instead of actual words, and there is no excuse for bad spelling.
Any negative dialogue or sarcasm is out too, as is sex talk.
I don't think it's that difficult for people to at least try to make the effort to treat each other with a little respect and some manners in mails.
