Looking for other forums about building robots

Any other forums that are more active than this one? I just can't believe I can't find other sites that are making robots and talking about them. 

I want to build another robot with tracks that will be able to run through snow and water and not worry about ruining the electronics. Also I can't seem to find tracks big enough. Its going to be a large robot and will need tracks similar to say a honda HP250 or similar tracked wheelbarrow. I just can't find tracks. 

 

I have come across some on ebay from snowblowers like this...

but they are too small 

Robot rebels and Coolkidsrobots are somewhat active.

I use project enclosures with rubber gaskets on them. I have a bot with three on it. Look on eBay for the boxes.
