Could pm's be set up so that when you return a pm it could me marked that you've responded in some way? My email on yahoo has a little arrow then you reply to an email. Thanks Padraic. I really love my forum here at Forumco.
Not at the moment. PM's are not really intended to replace email. In fact I think they go against the whole concept of a forum (i.e. public discussion).
Some people don't like to receive email from other members so pm's are a good thing. I get so many, some I save so I save info, addresses and such. It would be nice to have a way for people to know if they responded to a pm.
