I hope everyone is doing great today :) I'm new here

Hi guys,

I hope everyone is doing great today :slight_smile:

I'm new here and i'd like to know few things about wordpress and one of the thing i wish to know more about is , the GPL license. now my main questions are
1. is it okay to use wordpress to create WHAT EVER I WANT/PLEASE, am i allow to change /edit etc..
2. since wordpress is free(under the gpl license), am i allow to use wordpress and create websites for clients and make them pay for the services. eg. a saas application using wordpress where person will have to pay etc.. to use the platform and install plugins/themes
3. DO I HAVE/MUST KEEP THE text that says "powered by wordpress" in my website footer
4. anything else you'd like to share about the GPL will be great :slight_smile:

Cheers,

Thomas
