A Logo change represents the business change, perhaps addressing negative perceptions, strategic repositioning? You started off great with video reviews and content of builds, mfg. and service vendors that support and cater to the sand dunes crowds...that was good, but it stopped (yeah, we know the family issues, we get that). GD needs the younger crowds, go after the companies and Social Media sensations that the young 20 somethings pay attention to and follow. What is yore goal, to sell more t-shirts and swag? RDP is an active community, so i doubt that's true.
The two biggest obstacles GD has (IMHO) is the following or lack of:
AP Based Social Media Platforms. We do not have any presence on TikTok, Reddit, Discord, Snap Chat, YouTube or X. Whatever GD is up to, needs to be posted in short 15-30 second reels on those platforms, always giving links back to the forum, give an incentive to sign up as a member (Whip Flag, Coozie, Stickers). We have IG and Facebook, but they need attention. This is the biggest way to get GD out to the masses, at least you'll get the looks....GOOD content will get them to comeback. If a person has to log on to GD via the internet, webpage - this site will not grow. It's all about simplification, use plugs and features Xenforo has to allow sharing of forum content to social media.
Social Events and gatherings (Taco Tuesday) build personal relationships, those relationships bring folks back and then they start to participate, buy swag and stay invested. Everyone that is a longtime participating member, went to a Taco Tuesday, etc. They met a fellow board member, built a friendship and started camping together. We cannot be one big happy family, that dynamic never works, but a message board built on strangers/lurkers is just drama (Pirate4x4, HotBoat, MustangWorld, etc.)
So far all the examples shown are the typical AI generic stuff that looks like everyone else's AI generic stuff - boring, will not stand out at all. You could do what everyone else does out of their garage and copy-cat a Coors or Modelo logo and twist it to GD (lame crap, I'm being sarcastic).
I always thought we were Coca Cola (1886) around here, not Pepsi (Choice of New Generation)
Modernize the current logo, we had a more modern version that looked allot like the Dave and Busters scheme just like Fireball Ben said. Don't throw away an established 20 plus year brand.
