Hi and welcome to DnM, Jackie.
Since there are no scammers here (see this exception:
https://datingnmore.com/site/forum/topic/106 ) don't expect to be trampled with a ton of friend requests, private messages, winks, and the rest of the lot scammers are known for initiating. In fact, don't be too surprised if you find yourself being the one using the search function to enter your criteria. Reading profiles and then sending gifts, PM's, hearts, or whatever to sort of introduce yourself to the prospects.
you can upload, comment on, and vote on videos and pics. Participate here in the forums. Ask and answer poll questions. join or start a new group. write on peoples' walls, and probably more than that.
there are FAQ's at the bottom of every page if you'd like to learn about the software or the site itself. And there is a help forum if your question isn't answered in the FAQ's.
have fun while you are here.
