I still feel like I'm at that stage where I have to personally welcome each new member, but as the number of new sign-ups increases I know I won't be able to keep it up forever. Do you still personally welcome (that is, NOT by automated email or PM) each new member who posts an introduction, or do you leave that to other members?
Sometimes, I do welcome a new member however, sometimes I don't. I guess it mainly depends on the AMOUNT of work I have to do and how long I think that work would take.
Conclusion:
I welcome some members but not all members.
I try to welcome new members as I think it shows activity. However, if a board reaches a certain level of activity it's too hard to do so and not worth doing.
