2 part questions
1) I would like to see the jobs I posted in here but I do no know why. I cannot see a list of jobs I made. On the job manager dashboard i can see the jobs I made.
2) if i bought the premium job board manager, how much is it and is it a life time or subscription? does it include paid job postings
