I ran into a this limitation as well. I really wanted to post a youtube link in a post, but since I only had one or two posts, I wasn't allowed to post a link.
I really sympathize with the moderators for using this setting though. They are the volunteers feeling the workload month after month.
So now I've spent a couple of weeks, responding to a thread every couple of days. Maybe responding to threads I otherwise wouldn't have responded to, but tried to keep it useful to others. This one might bring me across the line.
