Been gone for some time

Hello,
I've been involved in moving to another state, and for the last couple years, I've been busy searching, viewing, and moving, so have not been involved in business opps, much, but am now back in full swing. I have a team already started in a new business, and a great upline support, who built her income to over $20,000 a month in her previous venture. I don't know if I can advertise on here. I'm not clear about that, but I would be willing to share this business with others. I searched this forum, and couldn't see where it was advertised.
I also would like to know how to put a website link as my signature. Tried it, and it wouldn't let me.
Any input would be good. thanks
