Welcome, Kevin! Glad to have you aboard. You’ve found a community chock full of genealogists who take their research seriously. And, not the least of it, you’ll find folks who will take time out from their own research to assist others, whether on the workings of WikiTree or others’ personal research.
The help index (https://www.wikitree.com/wiki/Help:Help_Index) will invaluable. And the video index (https://www.wikitree.com/wiki/Help:Video_Help) will also show you step by step how to create profiles, enter data, etc. If you can’t find what you need there, then G2G is the place for your questions. Take your time. There’s no rush to get all of your profiles up. It’s more important to get them right by working slowly.
Personally, I hope your experience here on WikiTree will be as fruitful as mine has been the short time I’ve been a member. The assistance and encouragement I’ve received here push me to do my very best. So, just in hop in and enjoy the ride.
