Glad to see you finally signed up! :D

There's not problem, you're at least attempting to contribute constructively here, and that is something that can definitely be worked with. I think the safest route to go through (if you feel a bit uncomfortable or unsure with adding something to an article) is to bring it up for discussion in the comments section of the article itself to see if the info is relevant enough to be added. Most editors here will help guide you in the right direction with the content and edits, so at the very least, it's nothing much to do with "permission", moreso than learning to decipher what's really needed or not. :-)
