Hi Steve,
Sure things. I've joined in a handful of different forums, some with picture sharing galleries. One of the problems is the expense - image files take up lots of space and bandwidth to download, so Russel might have to upgrade hosting for this forum.
You're always welcome to share you're electric bike builds and stories on my website - image hosting isn't nearly so much an issue:
Electric Bike Owners and Stories | Share Your Own Stories, and
Or you could share your pictures via a free Flickr account and link to it in your forum signature?
Hope this helps!
