powerrodsmike makes very valid points. Advertising your website in the forums is not allowed. You can place it in your public profile and refer the members to it in the forums. I understand that you had not referred to your website until you were asked but it is still not allowed for you to post you own website in the forums. Other members can do that but not you.
I also think it is time that you shared some of your techniques with the members. Your art is not just your working knowledge of working metal and technique. Otherwise it would be put in the "craft" category. It is how you use your mind to combine your metal working with your thoughts to produce a piece that is interesting and says something. How it combines form and in your case function.
The archway and the seats in that rod are very good examples of that.
Sharing your techniques will not put you in competition with our members. If someone does "steal" those techniques and starts copying your work they will be known as being a copycat with no imagination. Those type of people will never be YOUR competition.
