Many members are having posts hang, if it contains a % symbol anywhere in the post.
I am one of those member.
There are other issues, as well, that some members are seeing.
I've not seen any of the issues, while using the Woodall's portal. And, if I change the 'http' to 'https' in the address line, while using the RV.Net portal, I don't have any issues.
In the meantime, you can use a service such as bitly.com to shorten your Photobucket Albums or Photos URL which contain a space(%20), and you shouldn't have a problem posting them on RV.NET.
