You probably overpaid, even if you paid a small amount. When people think of forums, it usually comes with the idea that the forum will be filled with people who are passionate about the subject. I never heard of a person in world history who proclaimed that they were passionate about Geography. Sure, people are passionate about travel, passionate about the world, and generally fascinated by where everything is, but I'm not sure there are many people who are passionate about Geography.
The name doesn't have any sizzle, either. It is a little bland. Yes, if you are excited about Geography, you could start a forum and spend 40 years on it, but you could do that with any other name, so you wouldn't need this one. Your one other option would be to sell to someone who wanted to start their own forum. Once again, they will be fine using another name instead of paying your rent by buying this name off of you.
Unless you can convince me that GeographyForum.com brings something to the table that will allow someone to make more money than they would with any other similar name, then I'm afraid it isn't worth what you think. There are people out there who go broke who have poker forums with lots of members. That would seem to be tough to do, as poker creates lots of action, and you can sign up players with an affiliate link to play at various sites and get nice commissions. The word Geography is not associated with commerce in any way. Geography does not mean travel. But even if you had TravelForum.com you still have to execute a business plan. But TravelForum.com would bring extra value to your business because of the name. I have never heard an advertisement or read of one online or in a magazine or newspaper that included the word Geography. That is very telling.
If you started a forum relating to Geography, whatever success you had would be because of your hard work and effort. This name wouldn't give you any extra value in my opinion, and it rings a big flat to me. So, I believe the name is worth close to zero, and it will cost you money, time, and effort, to own it. That said, 99 percent of people don't accurately account for how much time and effort they put into their names. Someone might suggest it is worth a few hundred, but it is almost a certainty that you will put more than a few hundred dollars worth of man hours into the name just thinking about it.
You are at $50 or so right now. Just putting up this thread has cost you an hour of your time, as you check back for messages and write posts. Someone had to sell you this name. They were willing to let it go pretty cheap, I bet. I have a feeling you thought you pulled off a great deal, but the seller is likely very happy.
In my opinion, this is a dangerous name to own, because at first glance, it looks like a somewhat valuable name. But it won't ever help anyone make a dollar that they couldn't otherwise make with something else, so there is no reasonable expectation that someone will pay you a nice amount.
You asked twice for thoughts, so I thought I better step in. Good luck with it. Your target audience is a new domainer with very little knowledge. If I am wrong, then offers will be flooding into you after people read my post.
