Hi @cherrycupcake! Welcome to the forum! So glad that you're here
I think I know what might be happening. When you first join, you have certain privileges in the forum. As you spend more time participating, you earn cred that allows you to do more things. It's set up like this because we think you should get to know the community a little before jumping in (we wouldn't want someone who has never used Hopscotch to ask a million, unrelated question).
So, as a new user, you cannot start a new topic immediately. It kinda stinks when you sign up and are excited to ask a question and...can't. I think I'll change this so you can start a new topic sooner, though.
What do you think? Thanks for your input (and yours @t1_hopscotch)!!
