Plural Domains..

I thing I didn’t link about when buying a domain is to a least buying to singular form. It never thought about it being an issue until I mistyped one of my domains and I found someone had that someone had brought the singular form.If I would’ve bought the domain I can redirect to the actual site.I was kind of bum out because now has a similar names as mine.I brought t he domain first,the site has a decent traffic and pankpage.I think whoever owns the site is piggybacking off my site trying to feed of the traffic my get.But I can’t blame anyone else, but me I should’ve put in more though when buying a domain name.
