Just want to vouch for everyone here as well. I've bumped some pretty old topics from being a few months to almost a year old. Granted it was my custom vehicle thread, but I only did it because I didn't want to post a new thread just for another custom. I've done quite a bit of custom ships, and with bumping the topic it also gave others a chance to see my previous works. I've done it and it hasn't been an issue, everyone is real chill here. I actually wondered the same thing when I hadn't posted there in a while the first time, but all is good.
I agree with smeagol92055 though. If its 3 years old and there's nothing relevant to add, then yeah I can see the issue there. You should be fine though, TomO. Everyone here is laid back, enjoy your stay.
