Hi there,
I am sorry you are having trouble, but again, you have all the permissions you need, and you have all the permissions that every other member has to create your signature on your own.
Please understand, we are a group of volunteer moderators on a free, public yoga forum; we cannot possibly offer each of our members specific, individual signature building or code-writing assistance in addition to moderating. Since you have your question on the boards, it is likely another member will offer you more specific help, but please know that you do currently have all the tools you need–via David’s link–to build a signature that Vbulletin will support and display properly.
Best wishes,
Nichole
