I realise there aren't many still, almost 40, BUT however the amount of increasing members since the Portal intial release is amazing. I can only imagine it increasing even more once the SDK is released properly.
Also, remember to register to the ThinkingWithPortals Mapping Group on Steam Community.
I've also asked a Portal group in Steam if they'd like to put the url in there links section. The creator of the group said he would think about it.
It's a good way to contact other Portal Intrested people.
It's great to see that the community is growing.
It's really nice, yeah.
TWP is growing a lot larger by every day now it seems.
