Here are the functions of both user panels:
Deal Site user panel: user can save coupons, save favourite stores, customize email newsletter with stores of their choice
Forum user panel: your typical XenForo options like postings, activity log, etc.
Is it possible to combine the two? This is not simply accomplished by using an add-on to bridge the two like XenScripts because that's more for showing threads on WordPress. I'm trying to make one user panel that contains the functions of both so you don't have to go back and forth between the deal site or forum to use certain user account functions.
