Being an active member of the online brickfilming community, I thought I should make a long post to explain my views on this subject.
It doesn't cost money to add films to the Brickfilms.com directory, well at least it didn't. Since the new administration has come along, enraging most of the community with its poor communication and unfair action, the directory has been locked by them to avoid vandalism. (see this for more information) Most of the community has migrated to Bricks in Motion, where a new website is currently being built. It will have a new directory there when it is finished in the next one or two months.
Do you mean the current community at Brickfilms.com? I'm not surprised, there's no one there to welcome you and be friendly, except the occasional troll. The original brickfilms community (now at Bricks In Motion) are a great bunch of guys and gals, although it's a smaller group than here at EB. As the old saying within the brickfilming community goes, "It's not just a cult, it's a family". If you'd like to join us and share your films, we would welcome you with open arms!
I'd just like to say here that there is already a large repository of tutorials and stuff here. It was written by the brickfilms community before we all moved to BiM. And when BiM is finished, a new tutorial section will be built there!
Yeah, EB is more about LEGO than brickfilming, and brickfilming is really more about animation than LEGO. Think about it, is claymation really more about plasticine, or the story it's telling?
By making a brickfilming forum here, you're going to make a place for EBers to share their films and talk about brickfilming, but don't expect the BiM members to migrate here to talk about it too. We have our own forum dedicated to LEGO, but I don't see many EBers around there. If you're really interested in becoming a better brickfilmer, then it'd be a good idea to come over to BiM, as there are a lot of really experienced brickfilmers there who can give you a lot of advice. By learning about brickfilming here only, you're not going to have access to this treasure trove of information.
