IMO Trademarks are mainly not so much the words, but the "design/logo"
When I trademarked autocareforum, I trademarked the word with no design. It will cause more enforcement issues, but on the Internet, I'm covered.
Before you waste time and energy, go read what you have actually trademarked. One trademark that I have is a name and logo design, but when a competitor tried to use the "name" reversed somewhat, a letter from the lawyer, cease and desist was all it took, but namely because its a small town and they didn't want to waste the money fighting it.
Years ago, Bud took a florist to court over their use of "this bud is for you" The judge threw it out and stated "that if someone couldn't tell the difference, didn't deserve another "bud".
