Hi Jardine,

Aye - this lists email is just a recent addition. I still use the main 
contact email: kartbuilding[at]gmail.com for all emails, so it might have 
been that email which you used.

Good to know about the steering. I thought it might have been a bit heavy 
turing the threaded bar. A little grease goes a long way though.

As for emailing on photos, typically I get people to email the photos 
directly to the main email kartbuilding[at]gmail.com which takes up to 
10Mb. I then put them up on the kartbuilding gallery at 
http://www.kartbuilding.net/gallery/v/OtherPeoplesKarts/ and then email 
around the link via the lists. If you want to send on another few pictures 
I will put them up on the kartbuilding gallery all together.

Best of luck,
