You will find some people will forget or just change their minds, it's all good.
Some will like to join us and others will prefer to go there own way, doesn't really matter though, because we are just having some fun. The bigger the community gets, the better our chances are, of us all getting the upvote we all need to make a few dollars, but we don't need to go to hard at it, as some people get offended if we try to hard to convince them.
I just tell them where here and let them decide by themselves. I tend to tell every person that follows me and leave it at that, until they reply and show interest.
