You may be allowed to post Job Offerings, but Forum Rules, as i know them, are that Job Offer should be posted in the Job Forum.
The Description for the Job Forums says:
This is a place for position announcements from organizations and availability by instructors looks for new opportunities.
The other Sub Forums are for specific questions related to that topic. And afaik, everyone from CIN can post Job Offers in this releated forum.
"I am new to the Forums, so i did not know better"; is for me the lamest of all excuses..
May sound rude, but my opinion to such a behavior like yours is not positiv.
I am from a Generation, that learned, when you are new in forums, and to know not the rules, read the FAQ/ Netiquette or ask.
But do not Spam the Forum (Same content in different Forums).
May just me, but for me is your behaviour not professional. You wanna teach IT Certification Courses to people new in the IT world, but seem not to have an idea about professional behaviour or to teach netiquette.
There is no second chance for a first impression. You made yours.
