If you are new to WikiTree and the G2G forum... Welcome! You are invited to post here in G2G and introduce yourself. Say hello, let us know what names you are interested in, something about you, whatever you wish. When you are posting, put the word Introduction in the very last blank at the bottom where it asks for Surnames and project tags. You can also include surnames of interest here. Then click to "ask the question" :)
If you like to Greet people, welcome them, and offer assistance... you can follow the Tag Introduction. This can be done on your G2G Feed page at the top; there is a link provided to "add or edit" the Tags you are following. Whenever you see a post tagged Introduction you can up-vote it and respond with an answer or comment to help welcome people to WikiTree. Show them what a great community we are... it's fun!
Review past Introductions and warm welcomes by reading through all of the posts tagged Introduction. It's never too late to up-vote and say "hi".
