How will you know if a company accepts or rejects your request?
If they accepted you, you are added to the roster. Check it by going to the page, of by going to my profile here on WP. The Spartan company is listed next to your GT.
Edit: I just checked your profile you do not belong to any SC. They should send you a PM with a link to join.
Just go to the company’s page, if it doesn’t let you send a request to join, because you’ve already sent one, that means that they haven’t seen it yet, but if you already send a request and go back to their page and see that you can send another request, that means that they declined your request, and if you’re accepted, you’ll get a notification (notifications are to the left side of your profile).
If you get accepted you get a system message that welcomes you to the company.
If not then it might not notify you, I dunno.
