how do i link my forum and hosting account cuz everytime i try to register and link it. it says this account already has a forum account registered to it
Make sure you're following the right steps to link accounts. If you are, open a ticket, which will create a thread in the Community Support - Free Hosting forum (which is the correct forum for this issue, not here in programming help). If an admin needs to look into it, someone will escalate the thread.
