Let me be the first to say welcome and thanks for signing up!
Forge can take some getting used to. I still have alot to learn and that's what were here for. I've been sharing ideas and getting ideas from the other members here. We mess around with forge to find out what works and what doesn't. If you have any questions or ideas just create a post. I'm on the forums alot during the day because my job is cool like that, but there are other people who are far more helpful than myself. If your interested in some custom maps, you can start off by taking a look at my map. I'm far from done with it and still need to finish alot of things like spawn points and objectives for invasion, but overall I'm liking the feel of it. It's my first map and I'm looking for some feedback and suggestions. You can find my file on my file share:
