and click on my username (in the left - Norman). As you can see, if you have Safari or Firefox, the popup menu is pretty slow to open. If you have Chrome the popup is opened fast, but when you scroll with your mouse pointer in the options links, it slow down a little bit.
What could be the cause of this? Do you have some suggestions to fix this?
Now they are more fast to load. I had some scripts at the beginning of the page and I moved them at the bottom. But I think that I could still improve it a little bit.
About the errors in the page itself, most of them are alerts for deprecated elements eg. border="" or align="". This is a problem of vBulletin 3 (pretty old software). I’ll try to convert them all with time, but this is a long process.
